> 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.
