> When start in HA mode, Blob server does not put itself in shutdown hook. Line 158-164

> if (highAvailabilityMode == HighAvailabilityMode.NONE) {
> 	// Add shutdown hook to delete storage directory
> 	this.shutdownHook = BlobUtils.addShutdownHook(this, LOG);
> }
> else {
> 	this.shutdownHook = null;
> }
> That means, when kill the application in YARN, tmp fold will not be deleted.  What the
propose of this design?
