             Summary: Spark should cleanup output dir if job fails
                 Key: SPARK-7953
                 URL: https://issues.apache.org/jira/browse/SPARK-7953
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.3.0
            Reporter: Mohit Sabharwal


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.
