Mithun Radhakrishnan updated HIVE-11548:

Attachment: (was: HIVE-11548.1.patch)

 HCatLoader should support predicate pushdown.

 Key: HIVE-11548
 URL: https://issues.apache.org/jira/browse/HIVE-11548
 Project: Hive
  Issue Type: New Feature
  Components: HCatalog
Reporter: Mithun Radhakrishnan
Assignee: Mithun Radhakrishnan

 When one uses {{HCatInputFormat}}/{{HCatLoader}} to read from file-formats 
 that support predicate pushdown (such as ORC, with 
 {{hive.optimize.index.filter=true}}), one sees that the predicates aren't 
 actually pushed down into the storage layer.
 The forthcoming patch should allow for filter-pushdown, if any of the 
 partitions being scanned with {{HCatLoader}} support the functionality. The 
 patch should technically allow the same for users of {{HCatInputFormat}}, but 
 I don't currently have a neat interface to build a compound 
 predicate-expression. Will add this separately, if required.

Here's a tentative implementation.
