Owen O'Malley commented on HADOOP-1144:
---------------------------------------
I would rather take the approach of HADOOP-39 and have a configuration that
allows a job to have tips fail 4 times with out killing the rest of the job.
There also needs to be an interface to determine how many of the maps and
reduces failed.
> Hadoop should allow a configurable percentage of failed map tasks before
> declaring a job failed.

> Fix For: 0.13.0

>
> In our environment it can occur that some map tasks will fail repeatedly
> because of corrupt input data, which sometimes is non-critical as long as the
> amount is limited. In this case it is annoying that the whole Hadoop job
> fails and cannot be restarted till the corrupt data are identified and
> eliminated from the input. It would be extremely helpful if the job
> configuration would allow to indicate how many map tasks are allowed to fail.
