Review request for hive and Carl Steinbach.


Summary
-------

Pass the Login timeout to thrift/socket layer when connecting to the hive server.


This addresses bug HIVE-2110.

> 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".
