[jira] [Commented] (HDFS-5688) Wire-encription in QJM

    [ https://issues.apache.org/jira/browse/HDFS-5688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13877775#comment-13877775 ] 

Haohui Mai commented on HDFS-5688:
----------------------------------

There are multiple tests covering this feature (i.e., wire-encryption over RPC), therefore I believe that it might be a configuration error.

Can you post your configuration?

>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: ha, journal-node, security
>    Affects Versions: 2.2.0
>            Reporter: Juan Carlos Fernandez
>            Priority: Blocker
>              Labels: security

> When HA is implemented with QJM and using kerberos, it's not possible to set wire-encrypted data.
> If it's set property hadoop.rpc.protection to something different to authentication it doesn't work propertly, getting the error:
> ERROR security.UserGroupInformation: PriviledgedActionException as:principal@REALM (auth:KERBEROS) cause:javax.security.sasl.SaslException: No common protection layer between client and server
> With NFS as shared storage everything works like a charm
