Todd Lipcon commented on HADOOP-6269:
-------------------------------------
Hi Sreekanth,
What's the concern with the synchronization in the patch? This is not at all a
hot section (it should be called maybe 3-5 times in the course of an entire
execution) so I don't think the lock granularity really matters.
> Missing synchronization for defaultResources in Configuration.addResource

> Configuration.defaultResources is a simple ArrayList. In two places in
> Configuration it is accessed without appropriate synchronization, which we've
> seen to occasionally result in ConcurrentModificationExceptions.
