We had the Namenode URI wrong. Default by talend is nn_/_HOST, we used hdfs/_HOST and its working to authenticate normal Standard job connection to HDFS.
I have another issue now where when trying to connect to HDFS from a talend mapreduce job, its using SIMPLE authentication even though we have sepcified Kerberos authentication.
14/10/24 15:22:59 ERROR security.UserGroupInformation: PriviledgedActionException as:<UserName> (authIMPLE) causerg.apache.hadoop.security.AccessControlException: Client cannot authenticate via:
Error message is above.
Thanks,
