Subject [jira] [Commented] (HBASE-18490) Modifying a table descriptor to enable replicas does not create replica regions
Date Tue, 01 Aug 2017 19:18:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16109564#comment-16109564
] 

Ted Yu commented on HBASE-18490:
--------------------------------

{code}
  public static final String REGION_REPLICA_REPLICATION_CONF_KEY
    = "hbase.region.replica.replication.enabled";
{code}
The above constant is used in Replica tests.

Looks like addRegionsToMeta() can be added in MODIFY_TABLE_REOPEN_ALL_REGIONS state.

new Htable Descriptor is not taken into account and the table is enabled again with default
single region.
