Robert Kanter commented on MAPREDUCE-4942:
------------------------------------------
Looking at this some more, it seemed that {{cluster.getClient().getJobStatus}}
was the issue. Its signature in the {{ClientProtocol}} interface throws the
{{InterruptedException}}, but none of its implementations seem to actually
throw this exception. However, {{ugi.doAs}} is also throwing the
{{InterruptedException}} and I'd be more reluctant to change this because its
used all over the place.
> mapreduce.Job has a bunch of methods that throw InterruptedException so its
> incompatible with MR1

> Key: MAPREDUCE-4942
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4942
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 2.0.2-alpha
> Reporter: Robert Kanter
> Assignee: Robert Kanter
>
> 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}}.
