Now i don't have clear idea how the kerberos aunthentication will take place, where the tokens will be stored i.e., whether client-side or server side. How the credential cache would be managed,when two or more users access the application and access hadoop, because when we do kinit the old credential cache is replaced by the new one. What would be the complete flow?
