Subject [jira] [Commented] (HBASE-14240) Unactionable WARN messages in wal.ProcedureWALFormatReader
Date Tue, 18 Aug 2015 18:14:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14701712#comment-14701712
] 

Nick Dimiduk commented on HBASE-14240:
--------------------------------------

Shutdown should have been clean; from my run log I used hbase-daemon.sh. It was running 0.98.0,
before, so there would have been no WAL Procedure Store to stop. The installation was upgraded
to 1.1.2RC0 and process started again.
