------------------------------------
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.
