> When moving to HDFS HA or removing HA we end up changing the NN namespace.  This can
cause the HMaster not to start up fully due to trying to split phantom HLogs pointing to the
wrong FS - java.lang.IllegalArgumentException: Wrong FS: error messages.  The HLogs in question
might not even be on HDFS anymore.  You have to go in a manually clear out the ZK splitlogs
directory to get HBase to properly boot up.
