Imran Rashid commented on SPARK-8029:
-------------------------------------
This is a subset of the issues originally reported in
https://issues.apache.org/jira/browse/SPARK-7308, to have an issue with a
smaller scope, but hopefully still large enough to consider the design.
https://issues.apache.org/jira/browse/SPARK-7829 is the "ad-hoc" proposal of
the fix for this issue.
> ShuffleMapTasks must be robust to concurrent attempts on the same executor
> --------------------------------------------------------------------------

> Key: SPARK-8029
> URL: https://issues.apache.org/jira/browse/SPARK-8029
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.4.0
> Reporter: Imran Rashid
> Attachments:
> AlternativesforMakingShuffleMapTasksRobusttoMultipleAttempts.pdf
>
>
> When stages get retried, a task may have more than one attempt running at the
> same time, on the same executor. Currently this causes problems for
> ShuffleMapTasks, since all attempts try to write to the same output files.
