Ashutosh Chauhan commented on HIVE-5936:
----------------------------------------
Yeah, thats the idea 0 to mean empty table / partition -1 to mean unknown stat.
I looked at diff of {{stats_noscan_1}} and {{stats_noscan_2}} because of this
patch and it seems what we are getting after patch is correct stats, so for
this patch we can just regenerate those .q.out files. {{decimal_udf}} failure
looks unrelated to this patch.
