     [ https://issues.apache.org/jira/browse/CRUNCH-450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhong Wang updated CRUNCH-450:
------------------------------

    Attachment: CRUNCH-450-newapi.patch

I uploaded a new patch based on our previous discussion:
--
1. removed OrcTypeFamily
2. added a new class OrcWritable to deal with serialization
3. PTypes for orc format is derived from Writables

Just a quick version, still need some more work. Please let me know your ideas, so I can continue
my work
