> 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.
