Description

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?
