> It is found that if Hive Metastore is restarted then Drillbit also needs to be restarted
to further query and connect to hive metastore. 
> Repro Steps:
> ===========
> 1) Start HiveMetastore and drillbit.
> 2) Start Drillbit client with Scheman as hive and run a simple query like "show databases"
>    Command to start client: sqlline -u "jdbc:drill:schema=hive;drillbit=<name>"
> 3) restart hive metastore
> 4) Execute same query "show databases" on existing drillclient or new one. You will see
that hive default database is not listed. If you query any hive data then it will fail.
