> TableMapReduceUtil#initCredentialsForCluster uses job's configuration instead
> of conf in argument for UserProvider.
> This causes that token is not obtained for secure cluster in case of job's
> configuration contains hbase.security.authentication=simple.
> Because userProvider.isHBaseSecurityEnabled() checks that
> hbase.security.authentication is kerberos.
> If conf is configured for secure cluster, hbase.security.authentication is
> kerberos and it's natural to use conf for UserProvider instead of job's
> configuration in this method.
