> Hadoop auto-renews a ticket cache TGT.  However, a TGT acquired via keytab is just allowed
to expire.  To compensate, any exception during a kerberos RPC connection triggers a relogin.
> Prior to HADOOP-9698, the RPC client "knew" the SASL client was attempting authMethod
kerberos.  Now the SASL client negotiates and returns the authMethod to the RPC Client.  When
an exception occurs, such as TGT expired, the Client doesn't know what the SASL client was
attempting so no relogin is attempted.  After 24 hours, keytab based services that act as
clients (ex. RM for token renewal) go dead.
