Mahadev konar updated MAPREDUCE-1960:
-------------------------------------
Attachment: MAPREDUCE-1960-yahoo-hadoop-0.20S.patch
this patch adds a limit parameter at the jobtracker and throws an exception on
job submission if the job.xml exceeds this size. The size is set to a default
of 10MB. So any job that has a job.xml greater than 10MB will fail on
submission.
This patch is for yahoo-0.20 branch with tests. Will upload a patch for trunk
soon.
> Limit the size of jobconf.
