I have a Kerberos enabled cluster with HDFS service installed on host1.

when i try to perform some operations on HDFS server, its failing with below error.

17/08/08 11:19:34 WARN ipc.Client: Exception encountered while connecting to the server : javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]

@Akhil S Naik

Please do a kinit with the hDFS keytab and see if it works:

Get Principal Name

# klist -kte /etc/security/keytabs/hdfs.headless.keytab 
Keytab name: FILE:/etc/security/keytabs/hdfs.headless.keytab
KVNO Timestamp  Principal

.

- Do a kinit

# kinit -kt /etc/security/keytabs/hdfs.headless.keytab  [email protected]

.

Check the ticket.

# klist
