data and load data into HDFS, and update the configuration.

    This seems like something that could cause a really annoying problem for a user. Is there
no simple action we can take in this PR to stop Ambari from clobbering things?
    
    Obviously, deploying/updating the geo database in an Ambari "service action" would be
ideal. Would be nice to have one way to do it that does not break on restart.
    
    Or maybe we need to accept this for now and once we have Ansible deployments using the
MPack, we can implement an Ambari "service action" for this?
