Hi [~pgaref], will ORC-14 be integrated into this patch?

>  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.
