Subject [jira] [Created] (DRILL-1811) select A, * from ... crashes JVM
Date Fri, 05 Dec 2014 01:26:12 GMT
Sean Hsuan-Yi Chu created DRILL-1811:
----------------------------------------

             Summary: select A, * from ... crashes JVM
                 Key: DRILL-1811
                 URL: https://issues.apache.org/jira/browse/DRILL-1811
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Operators
            Reporter: Sean Hsuan-Yi Chu
            Assignee: Sean Hsuan-Yi Chu
            Priority: Blocker
             Fix For: 0.8.0


while "select *, A from ..." works,  select A, * from ... crashes JVM. 

As I discussed with Aman, the reason for the crash is because drill is not aware of the wildcard
"*". So the operator Project "transfers" the requested column A to the output instead of "copy".


So when drill is trying to project to the second operand in the select clause (i.e., "*" ),
nothing will come out of that column.
