> Optimize the column stats update logic in table alteration
> ----------------------------------------------------------
>
> Key: HIVE-15530
> URL: https://issues.apache.org/jira/browse/HIVE-15530
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Reporter: Yibing Shi
> Assignee: Yibing Shi
> Attachments: HIVE-15530.1.patch
>
>
> Currently when a table is altered, if any of below conditions is true, HMS
> would try to update column statistics for the table:
> # database name is changed
> # table name is changed
> # old columns and new columns are not the same
> As a result, when a column is added to a table, Hive also tries to update
> column statistics, which is not necessary. We can loose the last condition by
> checking whether all existing columns are changed or not. If not, we don't
> have to update stats info.
