> HIVE-8202 supports conversion of join to SMB Join automatically, which relies
> on the configuration property:
> "hive.auto.convert.sortmerge.join.bigtable.selection.policy".
> This task is to support conversion based on map-hints, instead of this
> policy. As hints are deprecated, this would not be the primary policy in
> line with MapReduce, but can be available as a backup to achieve feature
> parity.
