> In the current implementation of HistoryServer, Application ACLs is picked 
> from event log rather than configuration:
> {code}
>             val uiAclsEnabled = 
> conf.getBoolean("spark.history.ui.acls.enable", false)
>             ui.getSecurityManager.setAcls(uiAclsEnabled)
>             // make sure to set admin acls before view acls so they are 
> properly picked up
>             
> ui.getSecurityManager.setAdminAcls(appListener.adminAcls.getOrElse(""))
>             ui.getSecurityManager.setViewAcls(attempt.sparkUser,
>               appListener.viewAcls.getOrElse(""))
>             
> ui.getSecurityManager.setAdminAclsGroups(appListener.adminAclsGroups.getOrElse(""))
>             
> ui.getSecurityManager.setViewAclsGroups(appListener.viewAclsGroups.getOrElse(""))
> {code}
> This will become a problem when ACLs is updated (newly added admin), only the 
> new application can be effected, the old applications were still using the 
> old ACLs. So these new admin still cannot check the logs of old applications.
> It is hard to say this is a bug, but in our scenario this is not the expected 
> behavior we wanted.
