>          Components: llap
>    Affects Versions: 2.2.0

> When there are no llap daemons running, if getInstances() in registry service is invoked this can result in InvalidACLException since no daemons created zpath yet. The root path will not exist when instance cache populates entries under root path. If the root path creation is moved to init/start then getInstances() can return empty instead of failing with exception.
