Alejandro Abdelnur commented on MAPREDUCE-4942:
-----------------------------------------------
Arun, this is then a catch22. If we don't fix it, we are breaking Hadoop 1
users moving to Hadoop 2. I guess we'll have have to decide what is more
important, to keep compatibility with Hadoop 1 or Hadoop 0.23. Y! folks may not
be happy with the following, but given the adoption of Hadoop 1 and Hadoop
0.23, we should incline to Hadoop 1. Thoughts?
> mapreduce.Job has a bunch of methods that throw InterruptedException so its
> incompatible with MR1

> The following methods in MR2's {{org.apache.hadoop.mapreduce.Job}} throw an
> {{InterruptedException}} but don't in MR1, which makes them incompatible.
> (Their Javadoc comments are also missing that they throw an
> {{InterruptedException}} anyway)
> I propose that we wrap the {{InterruptedException}} in a
> {{RuntimeException}}.
> {code}
