ajithme edited a comment on issue #24142: [SPARK-27194][core] Job failures when task attempts do not clean up spark-staging parquet files URL: https://github.com/apache/spark/pull/24142#issuecomment-474991798 @vanzin thanks for clarification, i was just trying to make sure that its is the 'bad' idea to delete Okay i see the point. So Currently i see in org.apache.spark.internal.io.HadoopMapReduceCommitProtocol#commitJob when ``dynamicPartitionOverwrite`` is true, we do this ``` fs.rename(new Path(stagingDir, part), finalPartPath) ``` This is where we will get the old and the new task file causing duplicates. Would it be better if we could eliminate speculated old tasks files from this operation.?
