Panagiotis Garefalakis updated HIVE-23553:
------------------------------------------
Parent: (was: HIVE-22731)
Issue Type: Improvement (was: Sub-task)
> Bump ORC version to 1.6
> -----------------------
>
> Key: HIVE-23553
> URL: https://issues.apache.org/jira/browse/HIVE-23553
> Project: Hive
> Issue Type: Improvement
> Reporter: Panagiotis Garefalakis
> Assignee: Panagiotis Garefalakis
> Priority: Major
>
> 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.
