    [ https://issues.apache.org/jira/browse/HBASE-11476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14096184#comment-14096184
] 

Jonathan Hsieh commented on HBASE-11476:
----------------------------------------

{code}
+          <para>You can specify the maximum number of versions of a value that HBase
retains, per column
+            family. When the maximum number of versions is reached, the oldest version is
deleted.
+            By default, only the newest version is kept.</para>
+        </listitem>
{code}

nit -- ..  When the maximum number of versions is reached, the oldest *versions are eventually*
deleted.  By default ...

I'm going to fix this on commit.  Thanks misty.

> Could use some updating and expansion to emphasize the differences between HBase and
an RDBMS. I found http://jimbojw.com/wiki/index.php?title=Understanding_Hbase_and_BigTable
which is just excellent and we should link to it.
