> Key: HDFS-4043
> URL: https://issues.apache.org/jira/browse/HDFS-4043
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: security
> Affects Versions: 2.0.0-alpha, 2.0.1-alpha, 2.0.2-alpha, 2.0.3-alpha,
> 3.4.0, 3.3.9
> Environment: CDH4U1 on Ubuntu 12.04
> Reporter: Ahad Rana

> The Namenode uses the loginAsNameNodeUser method in NameNode.java to login
> using the hdfs principal. This method in turn invokes SecurityUtil.login with
> a hostname (last parameter) obtained via a call to InetAddress.getHostName.
> This call does not always return the fully qualified host name, and thus
> causes the namenode to login to fail due to kerberos's inability to find a
> matching hdfs principal in the hdfs.keytab file. Instead it should use
> InetAddress.getCanonicalHostName. This is consistent with what is used
> internally by SecurityUtil.java to login in other services, such as the
> DataNode.
