             Summary: Comment at end of query causes query to be ignored
                 Key: ZEPPELIN-5299
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-5299
             Project: Zeppelin
          Issue Type: Bug
    Affects Versions: 0.9.0
         Environment: Bug found in Zeppelin 0.9.0-preview1, which is included 
in the AWS EMR 6.2.0 release.
            Reporter: Jon Courtney


A trailing comment at the end of a query causes the query to be ignored.  
Running a cell with such a query will cause Zeppelin to return immediately, 
without an error.

Example:
{code:java}
%sql
select
  'one'
  , 'two' -- comment{code}

Workaround: Adding a final ';' at the end of the query fixes the problem, like 
so:
{code:java}
%sql
select
  'one'
  , 'two' -- comment
;{code}
