ramkrishna.s.vasudevan updated HBASE-18490:
-------------------------------------------
Attachment: TestRegionReplicasWithRestartScenarios.java
Attaching a test case to illustrate the problem.
{code}
// Create table then get the single region for our new table.
//createTableDirectlyFromHTD(tableName);
enableReplicationByModification(tableName);
{code}
Currently the test will fail because we have created a table and then modify it
to enable replicaiton.
If you uncomment the line createTableDirectlyFromHTD() and comment the
enableReplicationByModification() you can see that the test passes because it
creates 3 regions as per the specified replicaIds.
> Modifying a table descriptor to enable replicas does not create replica
> regions
