[jira] [Updated] (MAPREDUCE-4942) mapreduce.Job has a bunch of methods that throw InterruptedException so its incompatible with MR1

Robert Kanter updated MAPREDUCE-4942:
-------------------------------------

    Attachment: MAPREDUCE-4942.patch

I saw that in JobClient, there were methods which simply called the corresponding methods in Job that we're interested in for this JIRA, but it was wrapping any thrown InterruptedExceptions in IOExceptions.  So, I think the best thing to do here is to have Job wrap the InterruptedExceptions in IOExceptions (and not RuntimeExceptions as discussed before) instead of having JobClient wrap them.  The patch does this.

> 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}}.
