Tim Armstrong has uploaded a new patch set (#2). Change subject: IMPALA-4049: fix empty batch handling NLJ build side ......................................................................
IMPALA-4049: fix empty batch handling NLJ build side Memory from the build side of a nested loop join is referenced by its output batches, so accumulated memory build side resources must be transferred to the caller. Special-cased handling of empty batches did not transfer the memory. The fix is to accumulate empty batches and transfer their resources in the same way as non-empty batches. The iterator required changes to handle empty batches in the list. Testing: Added a unit test that exercises the bug RowBatchList. Add a query test that causes a crash in the ASAN build and incorrect results in the debug build.
