------------------------------------
Summary: Support kerberos principal name pattern for
KerberosAuthenticationHandler
Key: HADOOP-15440
URL: https://issues.apache.org/jira/browse/HADOOP-15440
Project: Hadoop Common
Issue Type: Improvement
Components: security
Reporter: He Xiaoqiao
When setup HttpFS server or KMS server in security mode, we have to config
kerberos principal for these service, it doesn't support to convert Kerberos
principal name pattern to valid Kerberos principal names whereas
NameNode/DataNode and many other service can do that, so it makes confused for
users. so I propose to replace hostname pattern with hostname, which should be
fully-qualified domain name.
