Class KerberosIdentity

java.lang.Object

com.bigstep.datalake.KerberosIdentity

public class KerberosIdentity
extends Object

Created by alexandrubordei on 24/07/2016. This is an UserGroupInformation alternative that can only handle Kerberos with keytab and principal name. However it is not static and allows various combinations between secure and insecure clusters.
