----------------------------------
> Alter table change column comment should not try to get column stats for
> update
> -------------------------------------------------------------------------------

> Key: HIVE-16803
> URL: https://issues.apache.org/jira/browse/HIVE-16803
> Project: Hive
> Issue Type: Bug
> Components: Statistics
> Reporter: Chaoyu Tang
> Assignee: Chaoyu Tang
> Priority: Minor
>
> When running command like "alter table .. change .." (e.g. ALTER TABLE
> testtbl CHANGE col col string COMMENT 'change column comment';) to change a
> column's comment, Hive should not go to fetch the column stats for update
> since the comment change does not affect table/partition column stats.
