Description

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)
