stczwd opened a new pull request #23825: [SPARK-26912][CORE][HISTORY] Allow setting permission for event_log
URL: https://github.com/apache/spark/pull/23825
 
 
   ## What changes were proposed in this pull request?
   Spark_event_log is set to 770 permissions by default. This will be a problem in the following scenarios.
   1, the user has some ugis that can not be added to the same group
   2, the user, who created applications, does not allow others to see or modifie it, event they are in same group
   3, the user allows other ugi to subscribe to information
   
   Thus, we add a new configuration for the permission of spark_event_log.
   
   ## How was this patch tested?
   change permission tests and unit tests
