      Description

      Currently ImpalaD's open the frontend connections and this results in query failures. The preferred behaviour would be that the ports remain closed till the catalog is received and for any reason is the SS connectivity is not established after reasonable attempts and timeouts, then the impalad to simply shut down.

      This will help especially when we have multiple impala'd behind a LB and connections can be directed to daemons with the catalog when some servers/impala services are been restarted for any reason.
