> Reduce number of delete calls to NN during Context::clear
> ---------------------------------------------------------
>
> Key: HIVE-23196
> URL: https://issues.apache.org/jira/browse/HIVE-23196
> Project: Hive
> Issue Type: Improvement
> Reporter: Rajesh Balamohan
> Assignee: Attila Magyar
> Priority: Major
> Attachments: HIVE-23196.1.patch, HIVE-23196.2.patch
>
>
> {{Context::clear()}} ends up deleting same directories (or its subdirs)
> multiple times. It would be good to reduce the number of delete calls to NN
> for latency sensitive queries. This also has an impact on concurrent queries.
