[jira] Created: (HBASE-3370) ReplicationSource.openReader fails to locate HLogs when they aren't split yet

ReplicationSource.openReader fails to locate HLogs when they aren't split yet
-----------------------------------------------------------------------------

                 Key: HBASE-3370
                 URL: https://issues.apache.org/jira/browse/HBASE-3370
             Project: HBase
          Issue Type: Bug
            Reporter: Jean-Daniel Cryans
            Assignee: Jean-Daniel Cryans
             Fix For: 0.90.0


In ReplicationSource.openReader there's a special handling of HLogs location during a failover and it's currently broken as it will retry 10 times and if the log splitting isn't done by then then it will skip the file forever.

First issue is that it looks at the chain of failovers but not the oldest one.

Second issue is that the location is found starting from the current RS's folder, instead of the dead RS's folder.
