Subject [jira] [Created] (HBASE-11594) Unhandled NoNodeException in distributed log replay mode
Date Sat, 26 Jul 2014 00:13:38 GMT
Jeffrey Zhong created HBASE-11594:
-------------------------------------

             Summary: Unhandled NoNodeException in distributed log replay mode 
                 Key: HBASE-11594
                 URL: https://issues.apache.org/jira/browse/HBASE-11594
             Project: HBase
          Issue Type: Bug
            Reporter: Jeffrey Zhong
            Assignee: Jeffrey Zhong
            Priority: Minor


This issue happens when a RS doesn't have any WAL to be replayed. Master immediately finishes
recovery for the RS while a region in recovery is still opening. 

Below is the exception in region server log:

org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /hbase/recovering-regions/20fcfad9746b3d83fff84fb773af6c80/h2-suse-uns-1395117052-hbase-7.cs1cloud.internal,60020,1395141895633
