> The main issue here is that if any configuration types in the "clusterconfig" table (in the ambari-server DB) happen to not be selected (no versions of that config type have "selected"= "1", then this NullPointerException is thrown.
> The Ambari Server Upgrade code should probably handle this exception case more gracefully, by adding a check for null in the {code}UpgradeHelper{code} class, and returning a more useful error message.  Perhaps the customer should get a message indicating the problem with the config types.
