---------------------------------------
Summary: Provide an option to wipe out column stats for
partitioned tables in case of column removal
Key: HIVE-23959
URL: https://issues.apache.org/jira/browse/HIVE-23959
Project: Hive
Issue Type: Improvement
Reporter: Zoltan Haindrich
Assignee: Zoltan Haindrich
in case of column removal / replacement - an update for each partition is
neccessary; which could take a while.
goal here is to provide an option to switch to the bulk removal of column
statistics instead of working hard to retain as much as possible from the old
stats.
