> Binding aclManager to RMWebApp would cause problem if RM is switched. There
> could be some validation check may fail.
> I think , we should not bind aclManager for RMWebApp, instead we should get
> from RM instance.
> In RMWebApp,
> {code}
> if (rm != null) {
> bind(ResourceManager.class).toInstance(rm);
> bind(RMContext.class).toInstance(rm.getRMContext());
> bind(ApplicationACLsManager.class).toInstance(
> rm.getApplicationACLsManager());
> bind(QueueACLsManager.class).toInstance(rm.getQueueACLsManager());
> }
> {code}
> and in AppBlock#render below check may fail(Need to test and confirm)
> {code}
> if (callerUGI != null
> && !(this.aclsManager.checkAccess(callerUGI,
> ApplicationAccessType.VIEW_APP, app.getUser(), appID) ||
> this.queueACLsManager.checkAccess(callerUGI,
> QueueACL.ADMINISTER_QUEUE, app.getQueue()))) {
> puts("You (User " + remoteUser
> + ") are not authorized to view application " + appID);
> return;
> }
> {code}
