Szehon Ho created HIVE-8911: ------------------------------- Summary: Enable mapjoin hints Key: HIVE-8911 URL: https://issues.apache.org/jira/browse/HIVE-8911 Project: Hive Issue Type: Sub-task Components: Spark Affects Versions: spark-branch Reporter: Szehon Ho
Currently the big table selection in a mapjoin is based on stats. We should also enable the big-table selection based on hints. See class MapJoinProcessor. This is a logical-optimizer class, so we should be able to re-use this without too many changes to hook up with SparkMapJoinResolver. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
