Enis Soztutar commented on HBASE-18490:
---------------------------------------
This is implemented in HBASE-10361, and the test
{{TestMasterOperationsForRegionReplicas#testCreateTableWithMultipleReplicas()}}
have a section to increase the number of replicas.
bq. So if the config 'hbase.region.replica.replication.enabled' is not set then
ideally we should not allow any region replica itself? Or even without this
config we can create replica regions?
Region replica replication is an "optional" feature for region replicas. Region
replicas can keep sync'ing with the primary replica using either "periodic
store file refreshing", or through region replica replication. So in theory,
the region replica setup is not dependent on region replica replication.
