Change subject: IMPALA-3586: Clean up union-node.h/cc to enable improvements. ...................................................................... IMPALA-3586: Clean up union-node.h/cc to enable improvements. This patch does not address IMPALA-3586, but it cleans up the code in union-node.h/cc to make it easier to implement those perf improvements. The major simplification is to remove conjunct evaluation since the planner does not assigns conjuncts to a union-node anymore. Conjuncts are always pushed to the union operands.
