Description

Currently Woker.StatsUpdater will run analyze table ... compute statistics for columns ... at the end of each Major compaction to update stats on columns that already have stats.

 

It would be useful to add a config option that allows better control over this.  I could have 3 values: don't update col stats, update existing col stats, update all col stats.

Should this have ability to update table level stats?  Is that needed given HIVE-19532?
