             Summary: Make EventLoggingListener.codecMap thread-safe
                 Key: SPARK-34125
                 URL: https://issues.apache.org/jira/browse/SPARK-34125
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.4.7
            Reporter: dzcxzl

2.x version of history server
EventLoggingListener.codecMap is of type mutable.HashMap, which is not thread safe
This will cause the history server to suddenly get stuck and not work.

The 3.x version was changed to EventLogFileReader.codecMap to ConcurrentHashMap type, so there is no such problem.
