---------------------------------------
Summary: S3A directory committer commit job fails if _temporary
directory created under set
Key: HADOOP-15469
URL: https://issues.apache.org/jira/browse/HADOOP-15469
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.1.0
Environment: spark test runs
Reporter: Steve Loughran
Assignee: Steve Loughran
The directory staging committer fails in commit job if any temporary files/dirs
have been created. Spark work can create such a dir for placement of absolute
files.
This is because commitJob() looks for the dest dir existing, not containing
non-hidden files.
As the comment says, "its kind of superfluous". More specifically, it means
jobs which would commit with the classic committer & overwrite=false will fail
Proposed fix: remove the check
