Ashutosh Chauhan commented on HIVE-13726:
-----------------------------------------
Thanks Rui for taking a look. I don't have precise numbers at the moment. On an
idle cluster, a single delete call was taking 10s of milliseconds. Done
serially, for 100s of files trashFilesUnderDir() was taking multiple seconds.
With 128 threads, it finished way faster. I will try to get more precise
measurement next time.
