Ben-Zvi opened a new pull request #1546: DRILL-6861: Hash-Join should not exit after an empty probe-side spilled partition URL: https://github.com/apache/drill/pull/1546 (The DIFF below is excessive due to indentation; but only two "lines" where actually changed). The original code below handles the spilled partitions by getting the next one (as build+probe "incoming"), and then recursively calling *innerNext()*. Each recursive call would end by (recursively) processing the next spilled partition. The DRILL-6755 change (line 556) caused an early exit when the probe side was empty. Thus in special cases when a probe-side of a spilled partition was empty, this change would terminate the recursive chain early, thus not processing the remaining partitions. The fix: When an empty probe-side spilled partition is seen - skip and process the next partition. A new check was added (line 624), and the code was altered into a "while" loop (line 618) to allow skipping.
