Rajesh Balamohan commented on TEZ-2584:
---------------------------------------
Patch in TEZ-2750 should address this as well. Need to test it out.
> Investigate: Reducers with local errors can run indefinitely
> ------------------------------------------------------------

> Key: TEZ-2584
> URL: https://issues.apache.org/jira/browse/TEZ-2584
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.8.0-alpha
> Reporter: Rajesh Balamohan
>
> When local errors (e.g disk error) are there, fetchers are expected to throw
> error and it is expected to restart the task elsewhere. With master branch,
> reducer continues to run indefinitely. Creating this jira to investigate the
> issue. I don't have a test case for this, but can be easily be simulated by
> throwing IOException purposefully in FetcherOrderedGrouped-->copyMapOutput
> (reserve()).
