[jira] [Created] (SPARK-39970) Introduce ThrottledLogger to prevent log message flooding caused by network issues

             Summary: Introduce ThrottledLogger to prevent log message flooding caused by network issues
                 Key: SPARK-39970
                 URL: https://issues.apache.org/jira/browse/SPARK-39970
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.4.0
            Reporter: Kai-Hsun Chen


When transient network error occurs, Spark may write out a large volume of error logs related to the network errors. The excessive logging can create further problems downstream, e.g. blow up our log storage. If we can combine / batch the network errors when they come in a burst, we only print out periodic summaries of errors that are happening repeatedly in a short time window.
