Review comment:
`1.8.3` as well as `1.8.1-drill-r0` are supposed to be a patch release on
top of `1.8.0`. Unfortunately `parquet-mr` does not properly follow semantic
versioning and have functional and API level changes in the patch releases. On
top of that, both `1.9.0` and `1.10.0` are not backward compatible with `1.8.0`
and/or `1.8.3`, so upgrade to `1.8.3` will not help us with the upgrade to
`1.10.0` later either or make it safer. I'd suggest to pay the price once.
Additionally, the latest parquet version may have a functionality to be used in
filter pushdown. @arina-ielchiieva what is your take?
Parquet libraries used by hive are shaded within `drill-hive-exec-shaded`,
so hive is guarded from the parquet-mr library upgrade.
