Bikas Saha commented on TEZ-3089:
---------------------------------
If either event has type other than start or finish then +1 will be return. Is
that desired or should that only be o1=finish and o2=start?
{code}+ if (o1.eventType.equals(EventType.START)
+ && o2.eventType.equals(EventType.FINISH)) {
+ return -1;
+ } else {
+ return 1;
+ }
{code}
> TaskConcurrencyAnalyzer can return negative task count with very large jobs
