Subject [jira] [Created] (HBASE-13627) Terminating RS results in redundant CLOSE RPC
Date Wed, 06 May 2015 00:26:00 GMT
Nick Dimiduk created HBASE-13627:

             Summary: Terminating RS results in redundant CLOSE RPC
                 Key: HBASE-13627
                 URL: https://issues.apache.org/jira/browse/HBASE-13627
             Project: HBase
          Issue Type: Bug
          Components: master
    Affects Versions: 1.1.0
            Reporter: Nick Dimiduk
            Priority: Minor
             Fix For: 2.0.0, 1.2.0, 1.1.1

Noticed while testing the 1.1.0RC0 bits. It seems we're issuing a redundant close RPC during
shutdown. This results in a logging warning for each region.
