Subject [jira] [Commented] (ACCUMULO-766) master is "leaking" ZooLock objects
Date Fri, 09 Nov 2012 16:10:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-766?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13494078#comment-13494078

Hudson commented on ACCUMULO-766:
---------------------------------

Integrated in Accumulo-Trunk #545 (See [https://builds.apache.org/job/Accumulo-Trunk/545/])
    ACCUMULO-766
There is a race condition between checking for a lock
and removing the node that holds the lock.  This causes
a spurious error message in the logs (and monitor). (Revision 1407489)

     Result = SUCCESS
