Panagiotis Garefalakis commented on HIVE-23553:
-----------------------------------------------
Hey [~yisong] – yes ORC 1.6 will have ORC-14 and thus the column-level
encryption feature but there is still some work missing in HIVE.
For example, there was a community discussion as part of HIVE-21848 to unify
encryption table properties (at least for ORC and Parquet).
However, we also need to cary over these properties to the derived Tables, and
this is still in progress (HIVE-21849).
> Upgrade ORC version 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.
