----------------------------------------

             Summary: upper, lower operators sometimes fail the JVM or return duplicated columns
                 Key: DRILL-1778
                 URL: https://issues.apache.org/jira/browse/DRILL-1778
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Operators
         Environment: Embedded Mode
            Reporter: Sean Hsuan-Yi Chu


*. The cases the operators pass through 
1. select *, upper(TABLE_NAME) from INFORMATION_SCHEMA.`TABLES`;
2. select upper(TABLE_NAME), * from INFORMATION_SCHEMA.`TABLES`;

*. The cases the operators fail
1. select upper(first_name),* from cp.`employee.json` limit 2
=> upper(first_name) was repeated "twice". 
2. select *, upper(first_name) from cp.`employee.json` limit 2
=> Crashed JVM entirely
