> 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.
