----------------------------
Summary: Introduce IsolatedThreadSafeRpcEndpoint to extend
IsolatedRpcEndpoint
Key: SPARK-41460
URL: https://issues.apache.org/jira/browse/SPARK-41460
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 3.3.1, 3.2.2, 3.1.3, 3.0.3, 2.4.8
Reporter: wuyi
The current RpcEndpoint extension to IsolatedRpcEndpoint always implies that
it's thread-safe. However, it's not explicit to developers. So people may
mistakenly override the IsolatedRpcEndpoint#threadCount with more than 1
threadCount leading to the thread-safety broken.
