    @mosermw I'm not sure that this is really necessary. The 
abstractOnStopped() method resets hdfsResources to new HdfsResources(null, 
null, null) - so every time that it's stopped, it gets reset. I think maybe the 
only change needed is the change below to config.set(disableCacheName, "true") 
??
