> 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}
