Amar Kamat commented on MAPREDUCE-130:
--------------------------------------
Upon restart the new jobtracker has no idea about the old completed jobs. I
have opened MAPREDUCE-700 to address this. One solution is to have just one
copy of jobconf with the jobtracker and delete it upon restart or job expiry.
The ideal place to have it is the jobtracker subdir which gets cleaned up upon
restart.
> Delete the jobconf copy from the log directory of the JobTracker when the job
> is retired

> The JobTracker (for web-ui viewing purposes), copies the jobconf from the
> hdfs and store it in the log directory. The file should be deleted when the
> job is retired (removed from memory).
