    shouldn't this be in a static member? we already have a place where the driver does a bunch of static initialization anyway...
    
    Then the object could just check if the library was successfully initialized, and if not, any attempt at initialization would fail.

> Drill should support Kerberos based authentication from clients. This means that both the ODBC and JDBC drivers as well as the web/REST interfaces should support inbound Kerberos. For Web this would most likely be SPNEGO while for ODBC and JDBC this will be more generic Kerberos.
> Since Hive and much of Hadoop supports Kerberos there is a potential for a lot of reuse of ideas if not implementation.
> Note that this is related to but not the same as https://issues.apache.org/jira/browse/DRILL-3584
