Vinod Kumar Vavilapalli commented on MAPREDUCE-5222:
----------------------------------------------------
One more comment: JobClient.submitJob and submitJobInternal both have their
signatures changed from MR1, we don't throw ClassNotFoundException and
InterruptedException anymore, which isn't breaking anything. But somehow
ClassNotFoundException thrown in the doAs in submitJob is not thrown/caught
anymore. Can you please check how it is handled? The InterruptedException is
caught and converted to IOException, which can perhaps be left like that.
