+    <title>Installing HBase on Windows using Cygwin</title>
+  </header>
+<p><a title="HBase project" href="http://hadoop.apache.org/hbase" target="_blank">HBase</a>
is a distributed, column-oriented store, modeled after Google's <a title="Google's BigTable"
href="http://labs.google.com/papers/bigtable.html" target="_blank">BigTable</a>.
HBase is built on top of <a title="Hadoop project" href="http://hadoop.apache.org">Hadoop</a>
for its <a title="Hadoop MapReduce project" href="http://hadoop.apache.org/mapreduce" target="_blank">MapReduce
</a>and <a title="Hadoop DFS project" href="http://hadoop.apache.org/hdfs">distributed
file system</a> implementation. All these projects are open-source and part of the <a
title="The Apache Software Foundation" href="http://www.apache.org/" target="_blank">Apache
Software Foundation</a>.</p>
+<p style="text-align: justify; ">As being distributed, large scale platforms, the Hadoop
and HBase projects mainly focus on <em><strong>*nix</strong></em><strong>
environments</strong> for production installations. However, being developed in <strong>Java</strong>,
both projects are fully <strong>portable</strong> across platforms and, hence,
also to the <strong>Windows operating system</strong>. For ease of development
the projects rely on <a title="Cygwin site" href="http://www.cygwin.com/" target="_blank">Cygwin</a>
to have a *nix-like environment on Windows to run the shell scripts.</p>
+<p style="text-align: justify; ">This document explains the <strong>intricacies
of running HBase on Windows using Cygwin</strong> as an all-in-one single-node installation
for testing and development. The HBase <a title="HBase Overview" href="http://hadoop.apache.org/hbase/docs/current/api/overview-summary.html#overview_description"
target="_blank">Overview</a> and <a title="HBase QuickStart" href="http://hadoop.apache.org/common/docs/current/quickstart.html"
target="_blank">QuickStart</a> guides on the other hand go a long way in explaning
how to setup <a title="HBase project" href="http://hadoop.apache.org/hbase" target="_blank">HBase</a>
in more complex deployment scenario's.</p>
+<title >Installation</title>
+<p style="text-align: justify; ">For running HBase on Windows, 3 technologies are required:
<strong>Java, Cygwin and SSH</strong>. The following paragraphs detail the installation
of each of the aforementioned technologies.</p>
+<p style="text-align: justify; ">HBase depends on the <a title="Java Platform, Standard
Edition, 6 Release" href="http://java.sun.com/javase/6/" target="_blank">Java Platform,
Standard Edition, 6 Release</a>. So the target system has to be provided with at least
the Java Runtime Environment (JRE); however if the system will also be used for development,
the Jave Development Kit (JDK) is preferred. You can download the latest versions for both
from <a title="Java SE Downloads" href="http://java.sun.com/javase/downloads/index.jsp"
target="_blank">Sun's download page</a>. Installation is a simple GUI wizard that
guides you through the process.</p>
+<p style="text-align: justify; ">Cygwin is probably the oddest technology in this solution
stack. It provides a dynamic link library that emulates most of a *nix environment on Windows.
On top of that a whole bunch of the most common *nix tools are supplied. Combined, the DLL
with the tools form a very *nix-alike environment on Windows.</p>
+<p style="text-align: justify; ">For installation, Cygwin provides the <a title="Cygwin
Setup Utility" href="http://cygwin.com/setup.exe" target="_blank"><strong><code>setup.exe</code>
utility</strong></a> that tracks the versions of all installed components on the
target system and provides the mechanism for <strong>installing</strong> or <strong>updating
</strong>everything from the mirror sites of Cygwin.</p>
+<p style="text-align: justify; ">To support installation, the <code>setup.exe</code>
utility uses 2 directories on the target system. The <strong>Root</strong> directory
for Cygwin (defaults to <code>C:\cygwin)</code> which will become <code>/</code>
within the eventual Cygwin installation; and the <strong>Local Package </strong>directory
(e.g. <code>C:\cygsetup</code> that is the cache where <code>setup.exe</code>
stores the packages before they are installed. The cache must not be the same folder as the
Cygwin root.</p>
+<p style="text-align: justify; ">Perform following steps to install Cygwin, which are
elaboratly detailed in the <a title="Setting Up Cygwin" href="http://cygwin.com/cygwin-ug-net/setup-net.html"
target="_self">2nd chapter</a> of the <a title="Cygwin User's Guide" href="http://cygwin.com/cygwin-ug-net/cygwin-ug-net.html"
target="_blank">Cygwin User's Guide</a>:</p>
+<ol style="text-align: justify; ">
+	<li>Make sure you have <code>Administrator</code> privileges on the target
+	<li>Choose and create you <strong>Root</strong> and <strong>Local
Package</strong> directories. A good suggestion is to use <code>C:\cygwin\root</code>
and <code>C:\cygwin\setup</code> folders.</li>
+	<li>Download the <code>setup.exe</code> utility and save it to the <strong>Local
Package</strong> directory.</li>
+	<li>Run the <code>setup.exe</code> utility,
+	<li>Choose  the <code>Install from Internet</code> option,</li>
+	<li>Choose your <strong>Root</strong> and <strong>Local Package</strong>
+	<li>and select an appropriate mirror.</li>
+	<li>Don't select any additional packages yet, as we only want to install Cygwin for
+	<li>Wait for download and install</li>
+	<li>Finish the installation</li>
+	<li>Optionally, you can now also add a shortcut to your Start menu pointing to the
<code>setup.exe</code> utility in the <strong>Local Package </strong>folder.</li>
+	<li>Add <code>CYGWIN_HOME</code> system-wide environment variable that
points to your <strong>Root </strong>directory.</li>
+	<li>Add <code>%CYGWIN_HOME%\bin</code> to the end of your <code>PATH</code>
environment variable.</li>
+	<li>Reboot the sytem after making changes to the environment variables otherwise the
OS will not be able to find the Cygwin utilities.</li>
+	<li>Test your installation by running your freshly created shortcuts or the <code>Cygwin.bat</code>
command in the <strong>Root</strong> folder. You should end up in a terminal window
that is running a <a title="Bash Reference Manual" href="http://www.gnu.org/software/bash/manual/bashref.html"
target="_blank">Bash shell</a>. Test the shell by issuing following commands:
+	<li><code>cd /</code> should take you to thr <strong>Root</strong>
directory in Cygwin;</li>
+	<li>the <code>LS</code> commands that should list all files and folders
in the current directory.</li>
+	<li>Use the <code>exit</code> command to end the terminal.</li>
+	<li>When needed, to <strong>uninstall</strong> Cygwin you can simply delete
the <strong>Root</strong> and <strong>Local Package</strong> directory,
and the <strong>shortcuts</strong> that were created during installation.</li>
+<p style="text-align: justify; ">HBase (and Hadoop) rely on <a title="Secure Shell"
href="http://nl.wikipedia.org/wiki/Secure_Shell" target="_blank"><strong>SSH</strong></a>
for interprocess/-node <strong>communication</strong> and launching<strong>
remote commands</strong>. SSH will be provisioned on the target system via Cygwin, which
supports running Cygwin programs as <strong>Windows services</strong>!</p>
+<ol style="text-align: justify; ">
+	<li>Rerun the <code><strong>setup.exe</strong></code><strong>
+	<li>Leave all parameters as is, skipping through the wizard using the <code>Next</code>
button until the <code>Select Packages</code> panel is shown.</li>
+	<li>Maximize the window and click the <code>View</code> button to toggle
to the list view, which is ordered alfabetically on <code>Package</code>, making
it easier to find the packages we'll need.</li>
+	<li>Select the following packages by clicking the status word (normally <code>Skip</code>)
so it's marked for installation. Use the <code>Next </code>button to download
and install the packages.
+	<li>OpenSSH</li>
+	<li>tcp_wrappers</li>
+	<li>diffutils</li>
+	<li>zlib</li>
+	<li>Wait for the install to complete and finish the installation.</li>
+<p style="text-align: justify; ">Download the <strong>latest release </strong>of
HBase from the <a title="HBase Releases" href="http://hadoop.apache.org/hbase/releases.html"
target="_blank">website</a>. As the HBase distributable is just a zipped archive,
installation is as simple as unpacking the archive so it ends up in its final <strong>installation</strong>
directory. Notice that HBase has to be installed in Cygwin and a good directory suggestion
is to use <code>/usr/local/</code> (or [<code><strong>Root</strong>
directory]\usr\local</code> in Windows slang). You should end up with a <code>/usr/local/hbase-<em>&lt;version&gt;</em></code>
installation in Cygwin.</p>
+This finishes installation. We go on with the configuration.
+<p style="text-align: justify; ">There are 3 parts left to configure: <strong>Java,
SSH and HBase</strong> itself. Following paragraphs explain eacht topic in detail.</p>
+<p style="text-align: justify; ">One important thing to remember in shell scripting
in general (i.e. *nix and Windows) is that managing, manipulating and assembling path names
that contains spaces can be very hard, due to the need to escape and quote those characters
and strings. So we try to stay away from spaces in path names. *nix environments can help
us out here very easily by using <strong>symbolic links</strong>.</p>
+<ol style="text-align: justify; ">
+	<li style="text-align: justify; ">Create a link in <code>/usr/local</code>
to the Java home directory by using the following command and substituting the name of your
chosen Java environment:
+<pre>LN -s /cygdrive/c/Program\ Files/Java/<em>&lt;jre name&gt; </em>/usr/local/<em>&lt;jre
+	<li>Test your java installation by changing directories to your Java folder <code>CD
/usr/local/<em>&lt;jre name&gt;</em></code> and issueing the command
<code>./bin/java -version</code>. This should output your version of the chosen
+<p style="text-align: justify; ">Configuring <strong>SSH </strong>is quite
elaborate, but primarily a question of launching it by default as a<strong> Windows
+<ol style="text-align: justify; ">
+	<li style="text-align: justify; ">On Windows Vista and above make sure you run the
Cygwin shell with <strong>elevated privileges</strong>, by right-clicking on the
shortcut an using <code>Run as Administrator</code>.</li>
+	<li style="text-align: justify; ">First of all, we have to make sure the <strong>rights
on some crucial files</strong> are correct. Use the commands underneath. You can verify
all rights by using the <code>LS -L</code> command on the different files. Also,
notice the auto-completion feature in the shell using <code>&lt;TAB&gt;</code>
is extremely handy in these situations.
+	<li><code>chmod +r /etc/passwd</code> to make the passwords file readable
for all</li>
+	<li><code>chmod u+w /etc/passwd</code> to make the passwords file writable
for the owner</li>
+	<li><code>chmod +r /etc/group</code> to make the groups file readable
for all</li>
+	<li><code>chmod u+w /etc/group</code> to make the groups file writable
for the owner</li>
+	<li><code>chmod 755 /var</code> to make the var folder writable to owner
and readable and executable to all</li>
+	<li>Edit the <strong>/etc/hosts.allow</strong> file using your favorite
editor (why not VI in the shell!) and make sure the following two lines are in there before
the <code>PARANOID</code> line:
+	<li><code>ALL : localhost : allow</code></li>
+	<li><code>ALL : [::1]/128 : allow</code></li>
+	<li>Next we have to <strong>configure SSH</strong> by using the script
+	<li>If this script asks to overwrite an existing <code>/etc/ssh_config</code>,
answer <code>yes</code>.</li>
+	<li>If this script asks to overwrite an existing <code>/etc/sshd_config</code>,
answer <code>yes</code>.</li>
+	<li>If this script asks to use privilege separation, answer <code>yes</code>.</li>
+	<li>If this script asks to install <code>sshd</code> as a service, answer
<code>yes</code>. Make sure you started your shell as Adminstrator!</li>
+	<li>If this script asks for the CYGWIN value, just <code>&lt;enter&gt;</code>
as the default is <code>ntsec</code>.</li>
+	<li>If this script asks to create the <code>sshd</code> account, answer
+	<li>If this script asks to use a different user name as service account, answer <code>no</code>
as the default will suffice.</li>
+	<li>If this script asks to create the <code>cyg_server</code> account,
answer <code>yes</code>. Enter a password for the account.</li>
+	<li><strong>Start the SSH service</strong> using <code>net start
sshd</code> or <code>cygrunsrv  --start  sshd</code>. Notice that <code>cygrunsrv</code>
is the utility that make the process run as a Windows service. Confirm that you see a message
stating that <code>the CYGWIN sshd service  was started succesfully.</code></li>
+	<li>Harmonize Windows and Cygwin<strong> user account</strong> by using
the commands:
+	<li><code>mkpasswd -cl &gt; /etc/passwd</code></li>
+	<li><code>mkgroup --local &gt; /etc/group</code></li>
+	<li><strong>Test </strong>the installation of SSH:
+	<li>Open a new Cygwin terminal</li>
+	<li>Use the command <code>whoami</code> to verify your userID</li>
+	<li>Issue an <code>ssh localhost</code> to connect to the system itself
+	<li>Answer <code>yes</code> when presented with the server's fingerprint</li>
+	<li>Issue your password when prompted</li>
+	<li>test a few commands in the remote session</li>
+	<li>The <code>exit</code> command should take you back to your first shell
in Cygwin</li>
+	<li><code>Exit</code> should terminate the Cygwin shell.</li>
+If all previous configurations are working properly, we just need some tinkering at the <strong>HBase
config</strong> files to properly resolve on Windows/Cygwin. All files and paths referenced
here start from the HBase <code>[<strong>installation</strong> directory]</code>
as working directory.
+	<li>HBase uses the <code>./conf/<strong>hbase-env.sh</strong></code>
to configure its dependencies on the runtime environment. Copy and uncomment following lines
just underneath their original, change them to fit your environemnt. They should read something
+	<li><code>export JAVA_HOME=/usr/local/<em>&lt;jre name&gt;</em></code></li>
+	<li><code>export HBASE_IDENT_STRING=$HOSTNAME</code> as this most likely
does not inlcude spaces.</li>
+	<li>HBase uses the ./conf/<code><strong>hbase-default.xml</strong></code>
file for configuration. Some properties do not resolve to existing directories because the
JVM runs on Windows. This is the major issue to keep in mind when working with Cygwin: within
the shell all paths are *nix-alike, hence relative to the root <code>/</code>.
However, every parameter that is to be consumed within the windows processes themself, need
to be Windows settings, hence <code>C:\</code>-alike. Change following propeties
in the configuration file, adjusting paths where necessary to conform with your own installation:
+	<li><code>hbase.rootdir</code> must read e.g. <code>file:///C:/cygwin/root/tmp/hbase/data</code></li>
+	<li><code>hbase.tmp.dir</code> must read <code>C:/cygwin/root/tmp/hbase/tmp</code></li>
+	<li><code>hbase.zookeeper.quorum</code> must read <code></code>
because for some reason <code>localhost</code> doesn't seem to resolve properly
on Cygwin.</li>
+	<li>Make sure the configured <code>hbase.rootdir</code> and <code>hbase.tmp.dir</code>
<strong>directories exist</strong> and have the proper<strong> rights</strong>
set up e.g. by issuing a <code>chmod 777</code> on them.</li>
+This should conclude the installation and configuration of HBase on Windows using Cygwin.
So it's time <strong>to test it</strong>.
+	<li>Start a Cygwin<strong> terminal</strong>, if you haven't already.</li>
+	<li>Change directory to HBase <strong>installation</strong> using <code>CD
/usr/local/hbase-<em>&lt;version&gt;</em></code>, preferably using
+	<li><strong>Start HBase</strong> using the command <code>./bin/start-hbase.sh</code>
+	<li>When prompted to accept the SSH fingerprint, answer <code>yes</code>.</li>
+	<li>When prompted, provide your password. Maybe multiple times.</li>
+	<li>When the command completes, the HBase server should have started.</li>
+	<li>However, to be absolutely certain, check the logs in the <code>./logs</code>
directory for any exceptions.</li>
+	<li>Next we <strong>start the HBase shell</strong> using the command <code>./bin/hbase
+	<li>We run some simple <strong>test commands</strong>
+	<li>Create a simple table using command <code>create 'test', 'data'</code></li>
+	<li>Verify the table exists using the command <code>list</code></li>
+	<li>Insert data into the table using e.g.
+<pre>put 'test', 'row1', 'data:1', 'value1'
+put 'test', 'row2', 'data:2', 'value2'
+put 'test', 'row3', 'data:3', 'value3'</pre>
+	<li>List all rows in the table using the command <code>scan 'test'</code>
that should list all the rows previously inserted. Notice how 3 new columns where added without
changing the schema!</li>
+	<li>Finally we get rid of the table by issuing <code>disable 'test'</code>
followed by <code>drop 'test'</code> and verified by <code>list</code>
which should give an empty listing.</li>
+	<li><strong>Leave the shell</strong> by <code>exit</code></li>
+	<li>To <strong>stop the HBase server</strong> issue the <code>./bin/stop-hbase.sh</code>
command. And wait for it to complete!!! Killing the process might corrupt your data on disk.</li>
+	<li>In case of <strong>problems</strong>,
+	<li>verify the HBase logs in the <code>./logs</code> directory.</li>
+	<li>Try to fix the problem</li>
+	<li>Get help on the forums or IRC (<code>#hbase@freenode.net</code>).
People are very active and keen to help out!</li>
+	<li>Stopr, restart and retest the server.</li>
+Now your <strong>HBase </strong>server is running, <strong>start coding</strong>
and build that next killer app on this particular, but scalable datastore!
