Description

When using connections secured with SSL, a connection close comprises a bi-directional SSL_shutdown(). The second part of the bi-directional shutdown requires that the client also close the socket explicitly, and the server blocks till it gets the close notification from the client.

We need to make sure that the impala-shell does the explicit close on an error.
