> MR calls abortTask and abortJob on the {{OutputCommitter}} to clean up the temporary output directories, but Spark doesn't seem to be doing that (when outputting an RDD to a Hadoop FS)
> For example: {{PairRDDFunctions.saveAsNewAPIHadoopDataset}} should call {{committer.abortTask(hadoopContext)}} in the finally block inside the writeShard closure. And also {{jobCommitter.abortJob(jobTaskContext, JobStatus.State.FAILED)}} should be called if the job fails.
> Additionally, MR removes the output dir if job fails, but Spark doesn't.
