             Summary: Use 'io.connectionTimeout' as a hint instead of `spark.network.timeout`
                 Key: SPARK-34894
                 URL: https://issues.apache.org/jira/browse/SPARK-34894
             Project: Spark
          Issue Type: Improvement
          Components: Shuffle, Spark Core
    Affects Versions: 3.1.1, 3.0.2, 2.4.7
            Reporter: Kent Yao


Currently, when a connection for TransportClient is marked as idled and closed, we suggest users adjust `spark.network.timeout` for all transport modules. As a lot of timeout configs will fallback to the `spark.network.timeout`, this could be a piece of overkill advice, we should give a more targeted one with `spark.${moduleName}.io.connectionTimeout`
