Izaak:

In hbase-env.sh, I'd just cut all of the JAVA_HOME references if (as you've figured) hbase
scripts just pick up the hadoop JAVA_HOME define: i.e. remove all of the below:
{code}
 # The only required environment variable is JAVA_HOME.  All others are
 # optional.  When running a distributed configuration it is best to
 # set JAVA_HOME in this file, so that it is correctly defined on
-# remote nodes.
+# remote nodes.  The definition of JAVA_HOME in the Hadoop configuration, 
+# however, no longer makes this a necessity.
 
-# The java implementation to use.  Required.
+# The java implementation to use.
 # export JAVA_HOME=/usr/lib/j2sdk1.5-sun
{code}

Here are a few other suggested edits:

Say 'At a minimum, the hbase.master property.... ' rather than: 'The hbase.master property
must be redefined...'

You could also say, 'for more on the hbase master, regionservers, etc., see ....' rather than
'master server read more' (This way, you probably only need to make the reference to the arch
doc. once only).

Otherwise, edits look great.

> The documentation for setting up HBase is relatively unclear and was in need of updating.
 I have attached a patch that modifies the package.html file (which contains instructional
sections such as "Getting Started") to improve the documentation.
