Description

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 handling wildcard "*" correctly. 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.
