Summary: Support explain analyze in Hive
Key: HIVE-14362
URL: https://issues.apache.org/jira/browse/HIVE-14362
Project: Hive
Issue Type: New Feature
Reporter: Pengcheng Xiong
Assignee: Pengcheng Xiong
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.
