Unused method?
> Must restart drillbits whenever a secure Hive metastore is restarted

> Key: DRILL-5496
> URL: https://issues.apache.org/jira/browse/DRILL-5496
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.10.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Fix For: 1.11.0
>
>
> DRILL-4964: "Drill fails to connect to hive metastore after hive metastore is
> restarted unless drillbits are restarted also" attempted to fix a bug in
> Drill in which Drill hangs if Hive is restarted. Now, we see that all
> subsequent "show schemas" queries fail.
> Steps to repro:
> 1. Build a secure cluster (we used MapR)
> 2. Install Hive and Drill services
> 3. Configure drill impersonation and authentication
> 4. Restart hivemeta service
> 5. Connect to drill and execute query involving hive storage, issue occurs
> 6. Restart the drill-bits services and execute the query, issue is no longer
> hit
> The problem occurs in the same place as the earlier fix, but might represent
> a slightly different use case: in this case the connection is secure.
