<para>Because HBase depends on Hadoop, it bundles an instance of the
Hadoop jar under its <filename>lib</filename> directory. The bundled
Hadoop was made from the Apache branch-0.20-append branch at the time
of the HBase's release. It is <emphasis>critical</emphasis> that the
version of Hadoop that is out on your cluster matches what is under
HBase. Replace the hadoop jar found in the HBase
<filename>lib</filename> directory with the hadoop jar you are running
out on your cluster to avoid version mismatch issues. Make sure you
of the HBase's release. The bundled jar is ONLY for use in standalone mode.
In distributed mode, it is <emphasis>critical</emphasis> that the version of Hadoop that is out
on your cluster match what is under HBase. Replace the hadoop jar found in the HBase
<filename>lib</filename> directory with the hadoop jar you are running on
your cluster to avoid version mismatch issues. Make sure you
replace the jar in HBase everywhere on your cluster. Hadoop version
mismatch issues have various manifestations but often all looks like
its hung up.</para>
