-----------------------------------------
Summary: ManifestCommitter to support / as a destination
Key: MAPREDUCE-7452
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7452
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: client
Affects Versions: 3.3.6
Reporter: Steve Loughran
you can't commit work to the root of an object store through the manifest
committer, as it will fail if the destination path exists, which always holds
for root.
proposed
* check for dest / in job setup; if the path is not root, use
createNewDirectory() as today
* if the path is root, delete all children but not the dir.
