> 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.
