By default Hadoop HTTP web-consoles (JobTracker, NameNode, TaskTrackers and DataNodes) allow access without any form of authentication.
We should use ResourceManager and NodeManager instead of JobTracker and TaskTracker.
Akira Ajisaka thanks a lot for review and commit.

Thank you for creating the patch.
+| `hadoop.http.authentication.signature.secret.file` | `$user.home/hadoop-http-auth-signature-secret` | The signature secret file for signing the authentication tokens. The same secret should be used for all nodes in the cluster, ResourceManager, NameNode, DataNode and TastTracker. This file should be readable only by the Unix user running the daemons.
Would you replace TastTracker with NodeManager?
Ok.. thanks..Uploaded the patch.. kindly review.
I'm thinking http://localhost:8088/cluster?user.name=babu (ResourceManager WebUI) is good for the replacement.
hmm, I was asking about "http://localhost:50030/jobtracker.jsp?user.name=babu`"
We should replace JobTracker and TaskTracker with ResourceManager and NodeManager, respectively.
Akira Ajisaka what can we replace for this..? I think, this was changed long back.
In addition, `http://localhost:50030/jobtracker.jsp?user.name=babu` should be updated.
