Amar Kamat updated HADOOP-5272:
-------------------------------

    Summary: JobTracker does not log TIP start information after restart  (was: TaskInProgress.isFirstAttempt()
does not log TIP start information after JobTracker restart)

> JobTracker does not log TIP start information after restart
> -----------------------------------------------------------

>                 Key: HADOOP-5272
>                 URL: https://issues.apache.org/jira/browse/HADOOP-5272
>             Project: Hadoop Core
>          Issue Type: Bug
>          Components: mapred
>            Reporter: Amar Kamat
>            Priority: Critical

> In case of JobTracker restart, attempt_0123456789_0001_m_000000_0 might not be the first
attempt to get scheduled as the attempt id offset changes after every restart. For example,

> upon first restart the new attempt id will be attempt_0123456789_0001_m_000000_1000.
Hence TIP start line never gets logged to the job history after the restart, TaskInProgress.isFirstAttempt()
always returns *false*.
