Summary: Use percentage for join conversion size thresholds Key: HIVE-20713 URL: https://issues.apache.org/jira/browse/HIVE-20713 Project: Hive Issue Type: Improvement Affects Versions: 4.0.0 Reporter: Prasanth Jayachandran There are many places in join conversion that rely on absolute byte sizes for join conversions (mapjoin, dynamic hashjoin etc.). When container sizes change, these join conversion thresholds have to be tuned accordingly according to the new container size. Instead, make the join conversions byte sizes a percentage/fraction of container size. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
