Subject [jira] [Commented] (HIVE-11504) Predicate pushing down doesn't work for float type for Parquet
Date Tue, 11 Aug 2015 16:31:46 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14682039#comment-14682039
] 

Ferdinand Xu commented on HIVE-11504:
-------------------------------------

Thanks [~spena] for your comments. I remove the default constructor since we can only evaluate
the real type for certain column with the help of schema. You can see that the predicate leaf
has a limited type and for float and double, they should use different builders for parquet.

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