Subject [jira] Created: (HADOOP-3080) Remove flush calls from JobHistory
Date Mon, 24 Mar 2008 16:39:24 GMT
Remove flush calls from JobHistory
----------------------------------

                 Key: HADOOP-3080
                 URL: https://issues.apache.org/jira/browse/HADOOP-3080
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.17.0
            Reporter: Devaraj Das
            Assignee: Amareshwari Sriramadasu
            Priority: Critical
             Fix For: 0.17.0


The flush calls from JobHistory should be removed. This has performance impact when lots of
events are being logged to the history files since the JT lock (e.g. lostTracker where the
tracker had ran a lot of tasks, and we call failedTask in a loop, etc.)
