> I only partially reviewed this. Will continue reviewing.
> One question: I see we do not care about column encryption related
arguments in multiple places. Is it because column encryption is not supported?
Hey @mustage good question with a complicated answer -- while creating this
I also did some digging to find out whats supported and what not. To sum up my
findings:
- It looks like we are currently able to encrypt entire tables and/or data
on hdfs using kms: HIVE-8065
- Support for column level encryption/decryption (passing some encryption
setting to the Table props and let Hive take care of the rest) started more
than a while ago as part of HIVE-6329
- There was a community discussion as part of HIVE-21848 to unify
encryption table properties (at least for ORC and Parquet) that concluded in
the accepted options
- However, these properties are still not propagated to the tables:
HIVE-21849
I believe part of the reason is that Hive already integrates with Apache
Ranger that can restrict user access to particular columns and also adds
data-masking on top.
However, I am more than happy discussing the revival of column encryption at
some point.

> 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.
