Owen O'Malley updated HADOOP-39:
--------------------------------
Description: I propose having a job option that when a tip fails 4 times,
stops trying to run that tip, but does not kill the job. (was: I had a map job
with side effects that meant that any speculative tasks would fail.
Currently, the job tracker kills the job when the speculative task fails 4
times.
It would be better to stop scheduling speculative tasks for that fragment, but
let the job continue as long as one of the the instances of that fragment
continue to run.)
Summary: Create a job-configurable best effort for job execution (was:
Job killed when backup tasks fail)
