Is memory for "context" object released during "sasl_dispose" of

> 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
