--------------------------------------
Hi [~ram_krish], which version did you check? I ran this with branch-1.2 and it
worked. Looked at the code,
https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/ModifyTableProcedure.java#L107
The handling of replica count change is there.
> Modifying a table descriptor to enable replicas does not create replica
> regions
