> -------------------------------------
>
> Key: HDFS-5150
> URL: https://issues.apache.org/jira/browse/HDFS-5150
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Kihwal Lee
> Priority: Blocker
> Attachments: HDFS-5150.patch
>
>
> For more flexible configuration of HA, the SPN for NN's internal SPNEGO needs
> to be per-nn. Currently the config should contain "_HOST" or configured
> differently per node.
> This change should not change the existing behavior unless the SPN is
> explicitly specified per NN under the HA configuration.
