Change subject: IMPALA-11803: Fix hitting DCHECK when running union on empty table with MT_DOP>1 ...................................................................... IMPALA-11803: Fix hitting DCHECK when running union on empty table with MT_DOP>1 The DCHECK was caused as the value of useMtScanNode_ was not getting set for empty tables. This was because of a condition for empty tables that returned from the computeNodeResourceProfile() function before setting up useMtScanNode_. It got rectified by placing the assignment of useMtScanNode_ before that condition. Testing: The fix is verified with an end-to-end test in test_mt_dop.py.
