Subject [jira] [Commented] (HIVE-12342) Set default value of hive.optimize.index.filter to true
Date Tue, 17 Jul 2018 09:21:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12342?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16546233#comment-16546233

Igor Kryvenko commented on HIVE-12342:
--------------------------------------

[~djaiswal] I don't think that it changes product behavior. It wasn't done to make tests pass
it was done because it made unstably execution plan for the {{TezCompiler}} . This change
affects nothing except Tez. As far as I understand it doesn't regress performance or anything else,
anyway it looks odd that we have the different plans for the same query.

Thanks, Igor.
