-----------------------------------------
[~gopalv] fyi
> spill to YARN directories, not tmp, when available

> Key: HIVE-13303
> URL: https://issues.apache.org/jira/browse/HIVE-13303
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin

> Attachments: HIVE-13303.patch

>
> RowContainer::setupWriter, HybridHashTableContainer::spillPartition,
> (KeyValueContainer|ObjectContainer)::setupOutput,
> VectorMapJoinRowBytesContainer::setupOutputFileStreams create files in tmp.
> Maybe some other code does it too, those are the ones I see on the execution
> path. When there are multiple YARN output directories and multiple tasks
> running on a machine, it's better to use the YARN directories. The only
> question is cleanup.
