[jira] [Created] (SPARK-41460) Introduce IsolatedThreadSafeRpcEndpoint to extend IsolatedRpcEndpoint

wuyi created SPARK-41460:
----------------------------

             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.
