Zhichun Wu commented on HIVE-4503:
----------------------------------
HIVE-4500 explicitly close history file and other resources in hiveserver2's
close session methods, but hiveserver still depends on GC to release history
file and SessionState's tmpOutputFile. There is a clean method in ThriftHive
interface introduced in HIVE-818 and we can use it to explicitly close a
session in hiveserver. We can also try to clean up old resource each time we
initize a HiveServerHandler in HiveServer.java:
{code}

Please correct me if I miss something.
