> Multithreaded mapper corrupts buffer pusher in nativetask
> ---------------------------------------------------------
>
> Key: MAPREDUCE-6757
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6757
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: nativetask
> Affects Versions: 3.0.0-alpha1
> Reporter: He Tianyi
> Attachments: MAPREDUCE-6757.0000.patch
>
>
> Multiple threads could be calling {{collect}} method of the same
> {{NativeMapOutputCollectorDelegator}} instance at the same time. In this
> case, buffer can be corrupted.
> This may occur when executing Hive queries with custom script.
> Adding 'synchronized' keyword to {{collect}} method would solve the problem.
