Bill Chambers updated SPARK-16234: ---------------------------------- Description: resolved... (was: given spark.speculative set to true, I'm running a large spark job with parquet and savemode overwrite. Spark will speculatively try to create a task to deal with a straggler. However, doing this comes with risk because EVEN THOUGH savemode overwrite is selected, if the straggler completes before the original task or the original task completes before the straggler then the job will fail due to the file already existing. java.io.IOException: /...some-file.../part-r-00049-401da178-3343-43a4-9c8d-277cc0173bf9.gz.parquet already exists) > Speculative Task may not be able to overwrite file > -------------------------------------------------- > > Key: SPARK-16234 > URL: https://issues.apache.org/jira/browse/SPARK-16234 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 2.0.0 > Reporter: Bill Chambers > > resolved... -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
