dzcxzl updated SPARK-34125:
---------------------------
Description:
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|https://issues.apache.org/jira/browse/SPARK-28869])
PID 117049 0x1c939
