Subject [jira] Commented: (HADOOP-5392) JobTracker crashes during recovery if job files are garbled
Date Tue, 10 Mar 2009 05:52:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12680382#action_12680382

Devaraj Das commented on HADOOP-5392:
-------------------------------------

+1 on the patch. Please ensure that "ant test" goes through with the patch.
BTW while reviewing this patch, I noticed that the JobHistory calls use the user's jobconf
to create/read history file paths on both hadoop.job.history.location and hadoop.job.history.user.location.
This should be fixed (in a separate jira) to use the JobTracker's conf for the history files
on hadoop.job.history.location.

> Jobtracker crashed in the recovery stage for a job with 0 byte job.xml. Ideally one would
expect the jobtracker to try and recover as many jobs as possible.
