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.
