Summary: Temporary (local) session files cleanup improvements
Key: HIVE-27317
URL: https://issues.apache.org/jira/browse/HIVE-27317
Project: Hive
Issue Type: Improvement
Reporter: Sercan Tekin
Assignee: Sercan Tekin
Attachments: HIVE-27317.patch
When Hive session is killed, no chance for shutdown hook to clean-up tmp files.
There is a Hive service to clean residual files https://issues.apache.org/jira/browse/HIVE-13429, and later on its execution is scheduled inside HS2 https://issues.apache.org/jira/browse/HIVE-15068 to make sure not to leave any temp file behind. But this service cleans up only HDFS temp files, there are still residual files/dirs in *HiveConf.ConfVars.LOCALSCRATCHDIR* location as follows;
