    +#### Model as a Service on Kerberos
    +MaaS works with kerberos, you have to remember to kinit with the metron
    +user.  There is one small issue out of the box, you get an error like so
    +when running `$METRON_HOME/bin/`:
    +Requested user metron is not whitelisted and has id 501,which is below the minimum allowed
    +In order to avoid this, you should change the Yarn configuration in
    +Ambari under "Advanced" and then "Advanced yarn-env" and adjust the
    +"Minimum user ID for submitting job" to 500 from 1000.  You should then
    +restart Yarn.
