Arun C Murthy commented on HADOOP-1304:
---------------------------------------
I'd think the right direction is to make them per-job, so only users who care
for higher/lower values get them and let it be usual defaults for others who
don't care...
> MAX_TASK_FAILURES should be configurable

> After a couple of weeks of failed attempts I was able to finish a large job
> only after I changed MAX_TASK_FAILURES to a higher value. In light of
> HADOOP-1144 (allowing a certain amount of task failures without failing the
> job) it would be even better if this value could be configured separately for
> mappers and reducers, because often a success of a job requires the success
> of all reducers but not of all mappers.
