> Issue Type: Bug
> Components: encryption
> Affects Versions: 2.6.0
> Reporter: Yi Yao

> 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.
> [LOG]
> ERROR[user=hdfs] Method:'GET' Exception:'java.lang.ClassCastException:
> javax.crypto.spec.SecretKeySpec cannot be cast to
> org.apache.hadoop.crypto.key.JavaKeyStoreProvider$KeyMetadata'
