Because HBase depends on Hadoop, it bundles an instance of the Hadoop jar under its
lib directory. The bundled jar is ONLY for use in standalone mode. In distributed mode, it is critical
that the version of Hadoop that is out on your cluster match what is
under HBase. Replace the hadoop jar found in the HBase lib 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.
