Tom White commented on MAPREDUCE-2375:
--------------------------------------
Ideally there wouldn't be an extra level of wrapping for ChecksumException
(which is thrown then caught in the same method). Either add a new catch block
and rethrow it, or log the extra detail in the IOException catch block and
rethrow there.
> Improve exception thrown by SpillRecord for bad spill index

> In trying to debug some issues on a cluster that was seeing shuffle fetch
> failures, I found the IOException thrown by the SpillRecord constructor to be
> insufficient. An improved exception would have more details about the file
> path, offset, etc.
