Major Description
Currently Drill's implementation of SSL between DrillClient and Drillbit is using the same user port which is used for non SSL traffic. If a setup is needed to support SSL encryption with Plain authentication and SASL encryption with Kerberos then that won't be possible. But with a separate port for SSL we can support above setup such that on SSL port encryption will always be using SSL and with any type of authentication. Whereas on non-SSL port things will work only with SASL (encryption + authentication).
