Pengcheng Xiong updated HIVE-14362: ----------------------------------- Status: Open (was: Patch Available) > 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 > Attachments: HIVE-14362.01.patch, HIVE-14362.02.patch, > HIVE-14362.03.patch, HIVE-14362.05.patch, HIVE-14362.06.patch, > compare_on_cluster.pdf > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
