Nemon Lou commented on HIVE-11768:
----------------------------------
For better understand:
The deletion of temp file can not fix this memory leak.It's the path string
that added to java.io.DeleteOnExitHook causing the leak.Once
"File.deleteOnExit()" is invoked ,the path string is leaked.No matter the temp
file will be deleted or not .
