Hi @Prashanthi B

How do you know it's not able to read credential cache? It appears that may be no kinit was done. Can you please provide steps you take to get to the point you get this error? What does the following command returns on the same machine where you get this error?

klist-A

[#3]

[root@lbl03bdput06c ~]# klist -A

[root@lbl03bdput06c ~]# klist klist: No credentials cache found (ticket cache FILE:/tmp/krb5cc_0)

[#4]

So there is no credential cache. You need to do a kinit first. Then you should run klist -A. Then it will show you the credential cache. It should work.

This is a connection issue. Can you connect to the cluster from command line from this machine?

Yes I am able to connect, this host is the Ambari Server
