> Apache Hive is currently on 1.5.X version and in order to take advantage of
> the latest ORC improvements such as column encryption we have to bump to
> 1.6.X.

> Even though ORC reader could work out of the box, HIVE LLAP is heavily
> depending on internal ORC APIs e.g., to retrieve and store File Footers,
> Tails, streams – un/compress RG data etc. As there ware many internal changes
> from 1.5 to 1.6 (Input stream offsets, relative BufferChunks etc.) the
> upgrade is not straightforward.
> This Umbrella Jira tracks this upgrade effort.
