>
> I recently saw a case where a bad node in the cluster produced corrupted
> shuffle data that caused the codec to throw IllegalArgumentException when
> trying to fetch. Fetchers currently only handle IOException and
> InternalError, and any other type of exception will cause the entire task to
> be torn down. We should consider catching Exception like MapReduce does to
> be more robust in light of other types of errors coming from the codec and
> allow retries to occur.
