@Vij 

Can you share your share your zookeeper_client_jaas.conf and zookeeper_jaas.conf they should be look like below

zookeeper_client_jaas.conf

Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=false
useTicketCache=true;
};

zookeeper_jaas.conf

Server {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
useTicketCache=false
keyTab="/etc/security/keytabs/zk.service.keytab"
principal="zookeeper/<host>@[REALM]";
};

Please compare and let me know

@Shelton  Thank you for your response but as of now first i am testing between server to server authentication and this is how my JAAS files looks like which i refereed from this wiki 

https://cwiki.apache.org/confluence/display/ZOOKEEPER/Server-Server+mutual+authentication

QuorumServer {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
keyTab="<keytab path>"
storeKey=true
useTicketCache=false
debug=false
principal="<principal>/_HOST@[REALM]";
};

QuorumLearner {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
keyTab="<keytab path>"
storeKey=true
useTicketCache=false
debug=false
principal="<principal>/_HOST@[REALM]";
};
