I hadn't seen that document, that's very cool to see, thanks!

It hasn't seen more than a typo fix in more than a year though (at least what's 
noted in the changelog) - is this tracked somewhere in JIRA (umbrella / per 
project / subtasks)?

Nevermind, found the one for Hive at least: HIVE-21348

>                 Key: HIVE-22006
>                 URL: https://issues.apache.org/jira/browse/HIVE-22006
>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: All Versions
>            Reporter: H. Vetinari
>            Priority: Major
>
> The interaction between HIVE / IMPALA / SPARK writing timestamps is a major 
> source of headaches in every scenario where such interaction cannot be 
> avoided.
> HIVE-9482 added hive.parquet.timestamp.skip.conversion, which *only* affects 
> the *reading* of timestamps.
> It formulates the next steps as:
> > Later fix will change the write path to not convert, and stop the 
> > read-conversion even for files written by Hive itself.
> At the very least, HIVE needs a switch to also turn off the conversion on 
> writes. That would at least allow a setup where all three of HIVE / IMPALA / 
> SPARK can be configured not to convert on read/write, and can hence safely 
> work on the same data
