> (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), the ugi will create proxy user via UserGroupInformation.createProxyUser(
> owner, UserGroupInformation.getLoginUser()),the old metastore client is never closed.
