Review Comment:
> In the absence of tests, this PR would have been declined by most of
committers.
Which tests? There are plenty of tests that exercise ORC files and
`TimestampWritableV2`. With the initial revision of the PR several tests failed
(please see Jenkins build history).
If there are specific tests that needs to be added, please explain.
Note that it will also block Spark upgrade to Hive 4.x till fix is
implemented.
