Eugene Koifman updated HIVE-7811:
---------------------------------
Description:
Compactions should trigger stats recalculation for columns that which already
have sats.
https://reviews.apache.org/r/25201/
Major compactions will cause the Compactor to see which columns already have
stats and run analyze command for those columns. If compacting a partition
then stats for that partition will be computed. If table is not partitioned,
then the whole table.
