Haibo Chen updated MAPREDUCE-6740:
----------------------------------
Status: Patch Available (was: Open)
Uploaded a new patch to address Karthik's comment. This patch
1) enforces task timeout to be as least twice as long as progress interval
2) sets the default value of progress report interval to 1% of the default
value of task timeout, which is still 3000 milliseconds.
Regardless of what value the user set the progress-report-interval to, the task
timeout will always be Max(2*progress-report-interval, configured value of
task timeout).
> Enforce mapreduce.task.timeout to be at least
> mapreduce.task.progress-report.interval
