@jongyoul no there isn't. Here's the snippet from UserGroupInformation,
which is essentially from Hadoop security. In future we will implement multiple
methods of security. At present for Kerberos security Kinit is a necessary
step. I intend to generalize this across other interpreters as well
subsequently.
`public static enum AuthenticationMethod {
SIMPLE,
KERBEROS,
TOKEN,
CERTIFICATE,
KERBEROS_SSL,
PROXY;
`
