Alex Behm has uploaded a new patch set (#2). Change subject: IMPALA-4336: Cast exprs after unnesting union operands. ......................................................................
IMPALA-4336: Cast exprs after unnesting union operands. The bug was that we cast the result exprs of operands before unnesting them. If we unnested an operands, casts were missing on those unnested operands' result exprs. The fix is to first unnest operands and then cast result exprs. Also clarifies the use of resultExprs vs. baseTblResultExprs.
