Subject [jira] Resolved: (MAPREDUCE-882) TestJobHistory fails sometimes
Date Thu, 20 Aug 2009 04:18:14 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-882?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amar Kamat resolved MAPREDUCE-882.
----------------------------------

    Resolution: Duplicate

The problem comes because taskIDsToAttemptIDs structure is shared in TestJobHistory across
tests. So if the job-id clash across testcases then the checks will fail. MAPREDUCE-745 should
fix this.
