> Currently HBase can run on top of Hadoop 0.20 with security APIs, but only using the "simple" authentication method.  There is currently no configuration or hooks for the HBase process to obtain Kerberos credentials so it can authenticate against secure Hadoop.
> We should extend the current {{org.apache.hadoop.hbase.security.User}} hooks to allow obtaining credentials from a keytab file when security is enabled.
