Allen Wittenauer created HDFS-6823:
--------------------------------------
Summary: dfs.web.authentication.kerberos.principal shows up in
logs for insecure HDFS
Key: HDFS-6823
URL: https://issues.apache.org/jira/browse/HDFS-6823
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Allen Wittenauer
Priority: Minor
Starting the namenode on a system not running Kerberos results in the following
showing up in the log:
{code}
2014-08-05 15:02:33,747 INFO org.apache.hadoop.hdfs.server.namenode.NameNode:
Clients are to use aw-mbp-work.local:9000 to access this namenode/service.
2014-08-05 15:02:33,831 WARN org.apache.hadoop.util.NativeCodeLoader: Unable to
load native-hadoop library for your platform... using builtin-java classes
where applicable
2014-08-05 15:02:33,948 INFO org.apache.hadoop.hdfs.DFSUtil: Starting web
server as: ${dfs.web.authentication.kerberos.principal}
2014-08-05 15:02:33,948 INFO org.apache.hadoop.hdfs.DFSUtil: Starting
Web-server for hdfs at: http://aw-mbp-work.local:50070
{code}
If Kerberos isn't configured, we shouldn't try to display the principal
message, never mind the raw text of the configuration option.
