Subject Re: Region count for a table not matching between prod and cob where one way replication is enabled from prod to cob
Date Wed, 27 Dec 2017 22:32:31 GMT
Regions in both clusters need not have to match, each server independently
manages its regions depending on split, compactions etc number of regions
in both servers won't be same. If you want to verify both servers are
replicated correctly you have to run below command

sudo -u hbase hbase
org.apache.hadoop.hbase.mapreduce.replication.VerifyReplication peer1
table1
