> Hive Client is indefenitely waiting for reading from Socket. Thread dump i  added below.
> Cause is:
>  
> 	In the HiveClient, when client socket is created, the read timeout is mentioned is 0. So the socket will indefinetly wait when the machine where Hive Server is running is "shutdown" or "network is unplugged". The same may not happen if the HiveServer alone is killed or gracefully shutdown. At this time, client will get "connection reset exception".
