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.
> Kerberos Authentication

> Key: DRILL-4280
> URL: https://issues.apache.org/jira/browse/DRILL-4280
> Project: Apache Drill
> Issue Type: Improvement
> Reporter: Keys Botzum
> Assignee: Sudheesh Katkam
> Labels: security
>
> 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
