Yongzhi Chen commented on HIVE-15997:
-------------------------------------
657 if (lDrvState.driverState == DriverState.INTERRUPT) { 657
if (lDrvState.driverState == DriverState.INTERRUPT) {
658 Thread.currentThread().interrupt();
659 return true; 658 return true;
Remove Thread.currentThread().interrupt(); // can solve some of the
resource leaks (depend on the cancel time), it let the query closed gracefully
instead of being interrupted during files clean up.
And
The fixes in zookeeper code can fix the lock leaks in my test case.
