Jorge Gabriel Siqueira commented on MAPREDUCE-5935:
---------------------------------------------------
Is there the possibility to js.fs be initialized after your check? If so, could
it cause some problem (because I think it will never be closed)?
> TestMRServerPorts#testTaskTrackerPorts fails with null pointer exception.

> Key: MAPREDUCE-5935
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5935
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: test
> Affects Versions: 1.1.1, 1.2.0, 1.2.1
> Reporter: Jinghui Wang

> The exception is caused by a race condition. The test case calls
> Jobtracker.offerservice in a seperate thread JTRunner, which initializes the
> class variable FileSystem fs. In the main thread it tries to close fs in the
> finally block of code, but at that point jt.fs might still not be
> initialized, thus causing the NPE.
