[jira] [Created] (HBASE-18231) Deprecate and throw unsupported operation when Admin#closeRegion is called.

JIRA jira@apache.org
stack created HBASE-18231:
-----------------------------

             Summary: Deprecate and throw unsupported operation when Admin#closeRegion is called.
                 Key: HBASE-18231
                 URL: https://issues.apache.org/jira/browse/HBASE-18231
             Project: HBase
          Issue Type: Sub-task
          Components: Admin
    Affects Versions: 2.0.0
            Reporter: stack
            Priority: Critical


[~uagashe] tripped over this today. Admin#closeRegion which we used to use in branch-1 will cause damage in AMv2 cluster. Instead you need to call unassign -- i.e. all cluster ops must go via the Master; no more going direct to RegionServer closing regions behind the Master's back.

Review all Admin ops to see what else skirts Master and deprecate and throw unsupported if called.
