jeremie simon commented on MAPREDUCE-6467: ------------------------------------------ I think updating to a more recent version of the common CLI is a good idea but will require more work as it might affect other classes and introduce some regressions. I think for the purpose of fixing this bug, it is probably easier to start removing the calls to OptionBuilder. > Submitting streaming job is not thread safe > ------------------------------------------- > > 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 > Priority: Minor > Labels: easyfix, streaming, thread-safety > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
