> this makes me think that in case there are operations using the tez session and then oozie does some DML operations, this can still happen, right? so the root cause looks independent of the fact that you reproduced it with DML-only scenario, so this fix is more likely hiding the problem, which is cleaning up scratch directories before tez sessions are closed, which is unexpected and needs to be fixed Ahh, true. This happens because the tez session is opened in a separate thread in async mode via beginStart() - https://github.com/apache/hive/blob/f78ca5df80c0bcb566f0915cda65112268df492c/cli/src/java/org/apache/hadoop/hive/cli/CliDriver.java#L785 And before closing the session we don't wait for the tez session to close. I have add a call for endStart() in the finally block now. That should probably fix the root cause. But it might also be beneficial to provide the setting to disable opening tez session everytime due to resource wastage. -- This is an automated message from the Apache Git Service.
