@ Nitin ROOT CAUSE:-
There
should be a table named by namespace for maintaining the info of tables, which
is already exists on /hbase directory , While starting the process HMaster it
will create the namespace directory under /hbase directory So it is showing the
Table Exists Exception.
SOLUTION:-
We have to
manually repair the /hbase metastore by using offline command as,
$HBASE_HOME/bin/hbase
org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair
Then start
the process of HMASTER. IF this is not working Use the zookeeper client for
removing it as,
From the
Hbase docker or any one of the docker.
zookeeper-3.4.6/bin/zkCli.sh
-server 192.168.1.90
ls /
rmr /hbase
ls /
exit
