HBase Master not running Exception
I am running mapreduce job to insert the data into HBase, Map phase is
running fine, but when the reducer starts it fails on all nodes except one
node and i notice below error on failed tasks. Out of 12 tasktrackers, one
tasktracker can connect to HBase and insert the data. Class path is set on
all nodes, but unable to figure out whats the root cause.  No issues with
HBase, i can scan the tables.

Caused by: java.lang.NoClassDefFoundError:
org/apache/hadoop/hbase/MasterNotRunningException
