-------------------------------------------

[~nishanthshajahan], I came across this issue recently and such status has gone by restarting HMaster (along with failover). Did you also restart the HMaster?

> I initially had a set of  5 region servers  which had a single table  which was pre split into 30 regions and was evenly distributed to all the regions with data.I then went ahead and removed/decommissioned a coupe of region servers,so in the end I have 3 region servers.Ran  hbase hbck and verified there were 0 inconsistencies.However when  'status' command is issued is from  hbase shell it shows a dead region server and the same is displayed in master UI as well.Fail over of hbase master did not fix the issue.On investigation we could see some WAL entries which was still pointing to the old region server.

> After removing these orphan entries from  hdfs and  master failover the dead region servers went away.I wonder if this  could have  caused any replication issues in the cluster.
