<title><code>NoClassDefFoundError</code> when trying to run 0.90.x on hadoop-0.20.205.x (or hadoop-1.0.x)</title>
<para>HBase 0.90.x does not ship with hadoop-0.20.205.x, etc. To make it run, you need to replace the hadoop
jars that HBase shipped with in its <filename>lib</filename> directory with those of the Hadoop you want to
run HBase on. If even after replacing Hadoop jars you get the below exception:

you need to copy under <filename>hbase/lib</filename>, the <filename>commons-configuration-X.jar</filename> you find
in your Hadoop's <filename>lib</filename> directory. That should fix the above complaint.
