stczwd commented on issue #23827: [SPARK-26912][CORE][HISTORY] Allow setting permission for event_log URL: https://github.com/apache/spark/pull/23827#issuecomment-467437924 @HeartSaVioR @vanzin In one of our usage scenarios, we used a history server as the history service. Users will run Spark with different clusters ugi, and they will check history in our history server. But there were problems in it: 1. many users can't or don't have any condition to modify hdfs permissions. Some of them don't know hdfs, while others don't know the user password. 2. It is impossible to modify the permissions to view the logs every time they run Spark. Therefore, it is better to support this configuration to solve these problems.
