Vaibhav Gumashta commented on HIVE-7076:
----------------------------------------
Other than [~thejas]' feedback, I did some verification with the patch. Without
the patch and with ATSHooks set, I can see an ever growing bunch of ATS logger
threads. With the patch, just one daemon thread. So looks good!
Test setup: I ran a test which creates 20 threads and fires up different short
jdbc queries for few hours.
