[jira] Commented: (HADOOP-6715) AccessControlList.toString() returns empty string when we set acl to "*"

    [ https://issues.apache.org/jira/browse/HADOOP-6715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12863673#action_12863673 ] 

Hemanth Yamijala commented on HADOOP-6715:
------------------------------------------

We could solve the problem of All, Users, None etc being valid user names by modifying the display string. Note that this is all primarily presentation layer changes. 

Firstly, I think displaying allowed users and groups separately in the UI would make it much more user friendly - rather than sticking to our internal representation.
So, we could say:

Allowed Users: a,b,c
Allowed Groups: d,e,f

When All or No users / groups have access, instead of saying:
"Users: All" or "Groups: None"
we could say
"All users can access job" or "No groups can access job"

Would this work ?

> AccessControlList.toString() returns empty string when we set the acl to "\*" and also when we set it to empty(i.e. " "). This is causing wrong values for ACLs shown on jobdetails.jsp and jobdetailshistory.jsp web pages when acls are set to "\*".
> I think AccessControlList.toString() needs to be changed to return "\*" when we set the acl to "\*".
