Peter Vary commented on HIVE-13157:
-----------------------------------
[~bharos92]: Seems unintuitive for me that StatsTask would update any other
data than the stats. What we can do is mark if we change anything on the
{{tbl}} object or it's children and in the end if we did not change anything
then we might not want to call alterTable. Also if we do not change anything
but the stats and we have a FollowingStatsTask then we can skip the alterTable
as well.
