[jira] [Resolved] (MAPREDUCE-102) NPE in tracker expiry thread.

     [ https://issues.apache.org/jira/browse/MAPREDUCE-102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Harsh J resolved MAPREDUCE-102.
-------------------------------

    Resolution: Not A Problem

Not a problem anymore on any of the recent stable releases - and we've not seen this error appear again either. The methods that remove a tracker use proper locking today that seems to prevent this from occurring anymore.

Gone stale, closing as 'Not a Problem' (anymore).
