Zoltan Haindrich commented on HIVE-21424:
-----------------------------------------
I think we should either fix aggregate column stats to not "skip" some
partitions; or disable it completely...
based on Ashutosh's comment; we probably won't be using it in long term:
https://issues.apache.org/jira/browse/HIVE-20585?focusedCommentId=16788761&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16788761
this cache right now causes corruption of statistic states in tests randomly,
so it would be better to disable it. for example: HIVE-20585
> Disable AggregateStatsCache by default
