A question about SessionManager

[Zhanghe (D)]

Hey Guys,

   I'm working with HiveServer2. I know the HiveServer holds a session for each 
client, and close it when the client execute 'CloseSession'.
   But if the client is forced to terminate, like Ctrl+Z or kill -9, the 
session in HiveServer will not be closed.
   Does there exists a problem? How can we solve it?

Thanks.
