> Support explain analyze in Hive
> -------------------------------

> Key: HIVE-14362
> URL: https://issues.apache.org/jira/browse/HIVE-14362
> Project: Hive

> Right now all the explain levels only support stats before query runs. We
> would like to have an explain analyze similar to Postgres for real stats
> after query runs. This will help to identify the major gap between
> estimated/real stats and make not only query optimization better but also
> query performance debugging easier.
