[jira] [Commented] (HIVE-18161) Remove hive.stats.atomic

    [ https://issues.apache.org/jira/browse/HIVE-18161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16312965#comment-16312965 ] 

Zoltan Haindrich commented on HIVE-18161:
-----------------------------------------

looks good, but I think the {{existStats()}} method should also be removed; since this way the new meaning would be {{atomic=true}} which was always {{false}} before

> It might have its purpose back then... when it was introduced; but currently enabling this property may at best prevent the stats collector from working properly :)
> And moreover: {{hive.stats.reliable}} is a very similar prop; and it would be better to use only one property which enables correctness checks.
