> TaskTracker should release slot if task is not launched

> Key: MAPREDUCE-2214
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2214
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 0.20.1
> Reporter: Ramkumar Vadali

> Attachments: MAPREDUCE-2214.patch

>
> TaskTracker.TaskInProgress.launchTask() does not launch a task if it is not
> in an expected state. However, in the case where the task is not launched,
> the slot is not released. We have observed this in production - the task was
> in SUCCEEDED state by the time launchTask() got to it and then the slot was
> never released. It is not clear how the task got into that state, but it is
> better to handle the case.
