i s it necessary to create a kerberos principal for hdfs on every node, as in hdfs/some-host@SOME-REALM? why not use one principal hdfs@SOME-REALM? that way i could distribute the same keytab file to all nodes which makes things a lot easier. thanks! koert
For helping manage this, Hadoop lets you specify principles of the format hdfs/_HOST@SOME-REALM. Here _HOST is a special string that Hadoop interprets and replaces it with the local hostname. You need to create principles per host though.
