---------------------------------
Resolution: Won't Fix
Out of date
> Provide last failure point when retry a mapper task
> ---------------------------------------------------

> Key: HADOOP-2162
> URL: https://issues.apache.org/jira/browse/HADOOP-2162
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Yiping Han
>
> Currently when a mapper failed and get restarted, the restarted mapper can
> find out if itself is a retry or the first try from the task name. We want to
> also know where in the input the last try failed.
> With the last failure point, our mapper can then do something different for
> the particular input. The failure point does not necessary to be very
> accurate. The reason we ask for this instead of let hadoop to deal with the
> failure record is, in such a way we can do something special for the failure
> record instead of simply skip it.
