Troubleshooting Kerberos Ticket  in Hadoop Cluster:


rajesh@hadoop_clinet_node:/export/home/rajesh> klist
klist: No credentials cache found (ticket cache FILE:/tmp/krb5cc_4040)
Kerberos 4 ticket cache: /tmp/tkt4040
klist: You have no tickets cached


rajesh@hadoop_clinet_node:/export/home/rajesh> kinit
Password for rajesh@LOCAL.DOMAIN:
<enter the domain password for the domain id rajesh>


rajesh@hadoop_clinet_node:/export/home/rajesh> klist
Ticket cache: FILE:/tmp/krb5cc_4040
Default principal: rajesh@LOCAL.DOMAIN

Valid starting     Expires            Service principal
