   > note: I tend to use distinct version numbers because snapshots might get 
cached and not updated - but that was an issue with the old ptest infra; I 
guess the current setup will handle that better...
   > 
   > anything will do which can serve a web page - I wanted to add 
https://raw.githubusercontent.com/pgaref/mave-repo/main/ it for you - however 
that page returns error 400 for everything...
   
   Hey Zoltan -- I noticed the 400 myself for listing and non-existing files 
(GitHub policy?) but maven pulling seems to work, for example, check 
https://raw.githubusercontent.com/pgaref/mave-repo/main/org/apache/orc/orc-core/maven-metadata-local.xml
   
   To be on the safe side though I created this Repsy public repo: 
https://repo.repsy.io/mvn/pgaref/repository
   Feel free to add this instead :)

>  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.
