Zhong Wang updated CRUNCH-450:
------------------------------
Description:
This JIRA adds ORC (Optimized Row Columnar) file format support in Crunch.
Three modes are supported for ORC serialization/deserialization:
--
1) Orcs.orcs(): using OrcStructs as the deserialized objects to provide high
performance
2) Orcs.reflects(): using Java reflection to support POJOs as the deserialized
objects
3) Orcs.tuples(): using Crunch Tuples as the deserialized objects to leverage
performance and user-friendliness
