Kerberos - Issue

[#1]

Can anyone explain whats the issue based on the error log from Namenode .

Also because of this issue , Namenode is in Safe Mode. 

I had manually configured Kerberos and made the Cluster kerberoised using Cloudera Manager 

Its really driving me insane . I am really tired of configuring kerberos in QuickStart 

Socket Reader #1 for port 8020: readAndProcess from client 192.168.19.131 threw exception [javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256 CTS mode with HMAC SHA1-96 is not supported/enabled)]]
