> Key: MAPREDUCE-6467
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6467
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: job submission
> Affects Versions: 2.7.1
> Reporter: jeremie simon
> Assignee: Ivo Udelsmann
> Priority: Minor
> Labels: easyfix, streaming, thread-safety
> Attachments: MAPREDUCE-6467.001.patch
>
>
> The submission of the streaming job is not thread safe.
> That is because the class StreamJob is using the OptionBuilder which is itself not thread safe.
> This can cause super tricky bugs.
> An easy fix would be to simply create instances of Option through the normal constructor and decorate the object if necessary.
> This fix should be applied on the functions createOption and createBoolOption.
