Subject [jira] Commented: (HADOOP-5272) JobTracker does not log TIP start information after restart
Date Fri, 20 Feb 2009 07:13:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675264#action_12675264

Ravi Gummadi commented on HADOOP-5272:

I tested this patch with TestJobHistory(of HADOOP-4191) and I see that with this patch, TIP
start is added properly.

> 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*.
