Description:
(1)When hadoop cluster kerberos is enable
(2) HiveServer2 config hive.server2.enable.doAs is set true
After a beeline scripte has been executed, hivemetastore connection is
created are in ESTABLISHED state and never closed.
If we submit a lot of task to hiveserver2 ,this will result in hive metastore
thrift thread(default is 1000) full ,thus new task will fail.
HiveServer2 use ThreadLocal<Hive> to store multithreading metastore
connection,the application should call Hive.closeCurrent() to close connection
after task finished.
When HiveServer2 impersonate is enable (hive.server2.enable.doAs is set true),
