-------------------------------
Summary: Support hints of SMBJoin
Key: HIVE-8640
URL: https://issues.apache.org/jira/browse/HIVE-8640
Project: Hive
Issue Type: Sub-task
Reporter: Szehon Ho
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.
