> Kerberos Authentication

>                 URL: https://issues.apache.org/jira/browse/DRILL-4280
>             Project: Apache Drill
>          Issue Type: Improvement

>            Assignee: Sudheesh Katkam

>
> 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
