> I'm using transparent encryption. If I create a key for KMS keystore via keytool and use the key to create an encryption zone. I get a ClassCastException rather than an exception with decent error message. I know we should use 'hadoop key create' to create a key. It's better to provide an decent error message to remind user to use the right way to create a KMS key.
