> Project: Hadoop HDFS
> Issue Type: Bug
> Components: security
> Reporter: Jing Zhao
> Assignee: Jing Zhao
>
> This is an issue reported by [~yeshavora]:
> In branch-1, Namenode fails to start with "HTTP/[email protected]" value of
> hadoop.http.authentication.kerberos.principal property in core-site.xml. It
> only supports hostname instead _HOST. Namenode can support
> "HTTP/[email protected]" value.
> Same issue also exists with datanodes.
