Yi Yao created HDFS-7067:
----------------------------
Summary: ClassCastException while using a key created by keytool
to create encryption zone.
Key: HDFS-7067
URL: https://issues.apache.org/jira/browse/HDFS-7067
Project: Hadoop HDFS
Issue Type: Bug
Components: encryption
Affects Versions: 2.6.0
Reporter: Yi Yao
Priority: Minor
Fix For: 2.6.0
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]

javax.crypto.spec.SecretKeySpec cannot be cast to
org.apache.hadoop.crypto.key.JavaKeyStoreProvider$KeyMetadata'
