Removed throwable field from FetchFailedException and added
MetadataFetchFailedException
FetchFailedException used to have a Throwable field, but in reality we
never propogate any of the throwable/exceptions back to the driver because
Executor explicitly looks for FetchFailedException and then sends FetchFailed
as the TaskEndReason.
This pull request removes the throwable and adds a
MetadataFetchFailedException that extends FetchFailedException (so now
MapOutputTracker throws MetadataFetchFailedException instead).
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/rxin/spark metadataFetchException
