Owen O'Malley commented on ORC-14:
----------------------------------

Hi, I have this mostly done, but need to finish some details and split the work out into manageable parts. I should get it committed in the next few weeks. After it is committed to master, we can start the ORC 1.6 release.

Integrating with Spark will be relatively easy. Hive will involve more changes because LLAP uses a lot of private interfaces into the ORC code.

> It would be useful to support column level encryption in ORC files. Since each column and its associated index is stored separately, encrypting a column separately isn't difficult. In terms of key distribution, it would make sense to use an external server like the one in HADOOP-9331.
