dzcxzl created SPARK-34125: ------------------------------ 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 Attachments: jstack.png, top.png
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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
