             Summary: Drill fails to execute SUBSTRING function 
                 Key: DRILL-542
                 URL: https://issues.apache.org/jira/browse/DRILL-542

          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Krystal


Ran the following query:
select substring(name, 5) from dfs.`voter` where age < 20;

The query just hangs.  The following error messages were observed in the drillbit.out:
