Description

TeraSort Job fails on S3 with below exception. Terasort creates OutputPath and writes partition filename but DirectoryStagingCommitter expects output path to not exist.

9/06/07 14:13:34 INFO mapreduce.Job: Job job_1559891760159_0011 failed with state FAILED due to: Job setup failed : org.apache.hadoop.fs.PathExistsException: `s3a://bucket/OUTPUT': Setting job as Task committer attempt_1559891760159_0011_m_000000_0: Destination path exists and committer conflict resolution mode is "fail"

Creating partition filename in /tmp or some other directory fixes the issue.
