[jira] [Created] (DRILL-2045) NPE when querying INFORMATION_SCHEMA table after drill upgrade

Victoria Markman created DRILL-2045:
---------------------------------------

             Summary: NPE when querying INFORMATION_SCHEMA table after drill upgrade
                 Key: DRILL-2045
                 URL: https://issues.apache.org/jira/browse/DRILL-2045
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 0.8.0
            Reporter: Victoria Markman


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)
