-------------------------------------
Ignore my previous comment. This doesn't actually hold true in the case of jvm
reuse.
> Task tracker should wait for the process to exit before declaring the task

> Key: HADOOP-2375
> URL: https://issues.apache.org/jira/browse/HADOOP-2375
> Project: Hadoop Core
> Issue Type: Bug
> Components: mapred
> Reporter: Owen O'Malley
> Assignee: Devaraj Das
> Fix For: 0.20.0
>
>
> Currently when a task declares it is done, the status in the task tracker is
> changed immediately. Instead it should wait for the subprocess to actually be
> done before it moves to one of the final states. This lead to a race
> condition where the task was still generating log data after the job tracker
> had reported the task as done.
