Subject [Hadoop Wiki] Update of "GettingStartedWithHadoop" by GlenMazza
Date Thu, 29 Nov 2012 01:57:59 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "GettingStartedWithHadoop" page has been changed by GlenMazza:

Short circuiting the reader to the more up-to-date Hadoop website if case he/she was unaware
of the tutorials there.

  ## page was renamed from Getting Started With Hadoop
  ## page was renamed from GettingStartedWithHadoop
+ Note: for the 1.0.x series of Hadoop the following articles will probably be easiest to
+  * [[http://hadoop.apache.org/docs/stable/single_node_setup.html|Hadoop Single-Node Setup]]
+  * [[http://hadoop.apache.org/docs/stable/cluster_setup.html|Hadoop Cluster Setup]]
+ The below instructions are primarily for the 0.2x series of Hadoop.
  = Downloading and installing Hadoop =
  Hadoop can be downloaded from one of the [[http://www.apache.org/dyn/closer.cgi/hadoop/|Apache
download mirrors]]. You may also download a [[http://people.apache.org/builds/lucene/hadoop/nightly/|nightly
build]] or check out the code from [[http://lucene.apache.org/hadoop/version_control.html|subversion]]
and build it with [[http://ant.apache.org|Ant]]. Select a directory to install Hadoop under
(let's say {{{/foo/bar/hadoop-install}}}) and untar the tarball in that directory. A directory
corresponding to the version of Hadoop downloaded will be created under the {{{/foo/bar/hadoop-install}}}
directory. For instance, if version 0.21.0 of Hadoop was downloaded untarring as described
above will create the directory {{{/foo/bar/hadoop-install/hadoop-0.21.0}}}. The examples
in this document assume the existence of an environment variable {{{$HADOOP_INSTALL}}} that
represents the path to all versions of Hadoop installed. In the above instance {{{HADOOP_INSTALL=/foo/bar/hadoop-install}}}.
They further assume the existence of a symlink named {{{hadoop}}} in {{{$HADOOP_INSTALL}}}
that points to the version of Hadoop being used. For instance, if version 0.21.0 is being
used then {{{$HADOOP_INSTALL/hadoop -> hadoop-0.21.0}}}. All tools used to run Hadoop will
be present in the directory {{{$HADOOP_INSTALL/hadoop/bin}}}. All configuration files for
Hadoop will be present in the directory {{{$HADOOP_INSTALL/hadoop/conf}}}.
