Change subject: IMPALA-9699: Skip '-1' values when aggregating num_null statistics ...................................................................... Patch Set 3: (1 comment) http://gerrit.cloudera.org:8080/#/c/15835/3/be/src/exec/incr-stats-util.cc File be/src/exec/incr-stats-util.cc: http://gerrit.cloudera.org:8080/#/c/15835/3/be/src/exec/incr-stats-util.cc@128 PS3, Line 128: if (num_new_nulls >= 0) num_nulls += num_new_nulls; > I haven't taken a close look at the code, but my concern was specifically w Ah, I see your point now, thank you for the clarification.
