[jira] [Created] (SPARK-8413) DirectParquetOutputCommitter doesn't clean up the file on task failure

Mingyu Kim created SPARK-8413:
---------------------------------

             Summary: DirectParquetOutputCommitter doesn't clean up the file on task failure
                 Key: SPARK-8413
                 URL: https://issues.apache.org/jira/browse/SPARK-8413
             Project: Spark
          Issue Type: Bug
    Affects Versions: 1.3.1
            Reporter: Mingyu Kim
            Priority: Critical


Here are the steps that lead to the failure.

1. Write a DataFrame using DirectParquetOutputCommitter
2. 1st attempt fails during the writes. e.g. https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/parquet/ParquetTableOperations.scala#L355
3. There is no clean-up logic on task failure, so the parquet part file written by the failed task is left half-written.
4. 2nd attempt fails with the following exception because the target file already exists.
