------------------------------------
Summary: Substitute _HOST with hostname for HTTP principals
Key: HADOOP-8381
URL: https://issues.apache.org/jira/browse/HADOOP-8381
Project: Hadoop Common
Issue Type: Sub-task
Components: security
Affects Versions: 0.22.0
Reporter: Benoy Antony
Assignee: Benoy Antony
Priority: Minor
Fix For: 0.22.1
SPNEGO based Web Authentication uses HTTP/fqdn@REALM as the kerberos principal
for each host.
Since it is difficult to modify the config for each host, a substitution
feature where _HOST gets replaced by fqdn is implemented.
The task is to provide similar feature for the kerberos principals used for
SPNEGO principals
