@jsensharma This problem is not solved and we are still unable to access Namenode UIs. In the last solution you mentioned to compare krb5.conf file from local cluster with that of hadoop cluster. But i could not find the krb5.conf file in hdfs.

Hi,
We are unable to access HDFS from a particular user 'edtuser' from putty after enabling kerberos. But we are able to access HDFS from 'root' user and 'hdfs' user. When we are trying to access HDFS from 'edtuser', the below error is coming:-
[edtuser@nladfmrvu11 ~]$ [edtuser@nladfmrvu11 ~]$ hadoop fs -ls / 19/08/22 09:48:06 WARN ipc.Client: Exception encountered while connecting to the server : org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS] 19/08/22 09:48:06 WARN ipc.Client: Exception encountered while connecting to the server : org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS] 19/08/22 09:48:06 INFO retry.RetryInvocationHandler: java.io.IOException: DestHost:destPort nladfmrvu12.mtn.co.za:8020 , LocalHost:localPort nladfmrvu11.mtn.co.za/10.244.8.52:0.

We are getting the below error whenever we are trying to access HDFS from console. This error is coming after enabling the kerberos authentication in the cluster. We are getting this error when we are trying to access from a customized user 'edtuser'. But we are not getting error when we are accessing error from 'root' user. and 'hdfs' user.Please find the error below:-
