Paul Rogers updated DRILL-5748:
-------------------------------
    Description: 
Launched a local Drillbit, using ZK. Entered the following query:

{code}
ALTER SYSTEM SET `exec.queue.enable` = true
{code}

Result:

{code}
Query Failed: An Error Occurred
java.lang.NullPointerException
{code}

Turns out, the problem is more general. The following produces the same error:

{code}
SELECT name, type FROM sys.options WHERE type in ('SYSTEM','SESSION') order by 
name;
{code}
