> 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.(-SPARK-28869-)
