Ramesh Mani commented on RANGER-1738:
-------------------------------------

[~coheigea] Is this still a valid patch or does it needs an update? I wanted to confirm before verifying this.

> In the newest hadoop version 3.0.0, YarnAuthorizationProvider has changed.
> The new YarnAuthorizationProvider.java has change the methods checkPermission and setPermission, 
> {code:title=YarnAuthorizationProvider.java|borderStyle=solid}
>   /**
>    * Check if user has the permission to access the target object.
>    * 
>    * @param accessRequest
>    *          the request object which contains all the access context info.
>    * @return true if user can access the object, otherwise false.

>   public abstract boolean checkPermission(AccessRequest accessRequest);

>    * @param permissions
>    *        A list of permissions on the target object.
>    * @param ugi User who sets the permissions.

> {code}
> But the RangerYarnAuthorizer extends YarnAuthorizationProvider impletement the old method.

> 	@Override
> 	public void setPermission(PrivilegedEntity entity, Map<AccessType, AccessControlList> permission, UserGroupInformation ugi) {
>        ...
> 	@Override
> 	public boolean checkPermission(AccessType accessType, PrivilegedEntity entity, UserGroupInformation ugi) {
> {code}
> I think yarn plugin should also impletement the new method. I will add a patch for it.
