Juan Carlos Fernandez updated HDFS-5688:
----------------------------------------

    Component/s: security
                 ha

> Wire-encriptation in QJM
> ------------------------
>
>                 Key: HDFS-5688
>                 URL: https://issues.apache.org/jira/browse/HDFS-5688
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: ha, journal-node, security
>    Affects Versions: 2.2.0
>            Reporter: Juan Carlos Fernandez
>              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
