Subject [jira] [Commented] (PIG-4092) Predicate pushdown for Parquet
Date Thu, 21 Jul 2016 05:24:20 GMT

    [ https://issues.apache.org/jira/browse/PIG-4092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15387189#comment-15387189
] 

Daniel Dai commented on PIG-4092:
---------------------------------

Pig's ParquetLoader is a wrapper. It's true PARQUET-397 implements LoadPredicatePushdown in
parquet's ParquetLoader, but we still need to declare the interface and pass the method call
to the wrapped ParquetLoader, this is not done, a simple patch is needed.
