[jira] [Commented] (HIVE-8600) Add option to log explain output for query

    [ https://issues.apache.org/jira/browse/HIVE-8600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14183738#comment-14183738 ] 

Mohit Sabharwal commented on HIVE-8600:
---------------------------------------

Attached patch adds an option to log the EXPLAIN EXTENDED output after the query has been semantically analyzed. It re-uses ExplainTask code that prints the plan.

> When diagnosing issues, it is useful to have the explain output for the query already available in log4j log.
