[jira] [Updated] (HIVE-8718) Refactoring: move mapLocalWork field
from MapWork to BaseWork
[ https://issues.apache.org/jira/browse/HIVE-8718?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xuefu Zhang updated HIVE-8718:
------------------------------
Component/s: (was: Spark)
Query Processor
Description:
Currently MapRedLocalWork instance is a field at MapWork. This is MR specific where small table input to map join is always from a MapWork, which isn't true for other execution engine where works doesn't need to be chopped at RS.
The refactoring moves the MapRedLocalWork to its parent class, BaseWork. Purely refactoring. No behavor change is expected. Test output might need to be updated though.
Priority: Minor (was: Major)
Affects Version/s: 0.15.0
