maswin opened a new pull request, #4015: URL: https://github.com/apache/hive/pull/4015
### What changes were proposed in this pull request? A setting to disable tez session being preemptively opened during startup of hive cli. ### Why are the changes needed? DML only operations won't need a tez session to be opened. Oozie action that launches hive cli for DML only operations need this setting. Sometimes before the tez session thread could completed, the oozie hive action completes its DML operations and clears the scratch folders causing the tez session to fail with following exception: Added a setting disable Tez session being opened during the startup of Hive cli. This is particularly needed when Hive action is being launched by Oozie to perform DML only operations. In that cases before the tez session thread could complete the launcher gets completed and clears all the scratch directories. This leads to a failure with following stack trace: ``` Added a setting disable Tez session being opened during the startup of Hive cli.
