Zoltan Haindrich commented on HIVE-23375:
-----------------------------------------
what happens in case there are 2 tasks loading the same hashtable? IIRC these
counters are aggregated; so we will see {{loadTime_1+loadTime_2}} is that ok?
...hmm...I'm wondering if it would be possible to introduce a tez counter which
could report the min/max/avg/var for the actual value - which could give
insight into what kind of values it have aggregated
