Zoltan Haindrich commented on HIVE-21424:
-----------------------------------------
note: aggregatestatscache is highly broken; the variance filter is practically
doesn't work because the cached/requested are integers => the division always
result in 0 value; and since maxVariance is a floating point .01 ; the
condition is never satisified

> Disable AggregateStatsCache by default
