Vinod Kumar Vavilapalli commented on MAPREDUCE-4942:
----------------------------------------------------
bq. And we are already 'breaking things' for 0.23, MAPREDUCE-5233.
Not sure about this particular JIRA anyways given it is focusing on
mapreduce.Job and so far I/we have focused extensively on mapred APIs.
And MAPREDUCE-5233 (among others) is related to mapred APIs. I've added folks
from Y!(who the only ones mostly looking at 0.23 compatibility) to all those
JIRAs which I saw to be breaking 0.23. We are looking at it on a case-by-case
basis.
> 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}}.
