> I'm filing this bug as a placeholder to investigate the reason of NPE on
> "select * from INFORMATION_SCHEMA.`TABLES`" on my cluster.
> My strong suspicion is that it is related to the way I upgrade drill on a cluster and
this is somehow scrambles zookeeper's state. 
> My steps are:
>     * stop drillbits
>     * uninstall drill rpm: "rpm -e <>"
>     * install a new rpm: "rpm -i <>"
>     * service mapr-warden restart (I don't stop warden before an upgrade)
