Subject [jira] [Commented] (HIVE-11504) Predicate pushing down doesn't work for float type for Parquet
Date Tue, 18 Aug 2015 18:41:45 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14701763#comment-14701763
] 

Owen O'Malley commented on HIVE-11504:
--------------------------------------

This patch seems problematic. 

The SARGs were better done with no distinction between int/long and float/double. What was
the original motivation for the change? 

I believe we should roll back both changes, so I'm -1 on this patch for now.

> Predicate builder should use PrimitiveTypeName type in parquet side to construct predicate
leaf instead of the type provided by PredicateLeaf.
