If any user/admins are not able to view the container logs. And the applications are running with Spark service. Looks like ACLs are not configured. Add this in your clusters: 


  1. Go to Cloudera Manager -> Spark -> Configuration -> Spark Client Advanced Configuration Snippet (Safety Valve) for spark-conf/spark-defaults.conf
    spark.acls.enable= true
  2. Set spark.ui.view.acls=username1,username2
  3. Set spark.modify.acls=user1,user2

 If you pass * as value it will give access to all the users. And both user[admin.acls] and groups[admin.acls.groups] accept both username and groups as comma-separated values.


Both user and group lists use a comma-separated list of entries. The wildcard character “*” allows access to anyone, and the single space “ “ allows access to no one.
