[jira] [Commented] (IMPALA-6033) Add query option that rejects queries against tables with missing statistics

["Peter Ebert (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IMPALA-6033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16498466#comment-16498466 ] 

Peter Ebert commented on IMPALA-6033:
-------------------------------------

I would say that there should be at least 3 options.

 
 # Run with/without stats
 # Run if and only if any stats are present (for example table too large for stats, manually entered row statistics)
 # Do not run if any stats are missing

> Add query option that rejects queries against tables with missing statistics
