Hey @saucam, partitioning support for the old Parquet support is quite
limited (only handles 1 partition column, whose type must be INT). PR #4308 and
upcoming follow-up PRs aim to provide full support for multi-level partitioning
and schema merging. Also, Parquet tables converted from Hive metastore tables
will retain their schema and location information inherited from metastore. We
plan to deprecate the old Parquet implementation by the new Parquet data source
in 1.3, and would like to remove the old one once the new implementation is
proved to be stable enough.
