BoYang created SPARK-33114: ------------------------------ Summary: Add metadata in MapStatus to support custom shuffle manager Key: SPARK-33114 URL: https://issues.apache.org/jira/browse/SPARK-33114 Project: Spark Issue Type: Improvement Components: Shuffle Affects Versions: 3.0.1 Reporter: BoYang
Current MapStatus class is tightly bound with local (sort merge) shuffle which uses BlockManagerId to store the shuffle data location. It could not support other custom shuffle manager implementation. We could add "metadata" to MapStatus and allow different shuffle manager implementation to store information related to them. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
