> When creating an upgrade between stack versions (such as HDP 2.2 to 2.3), if the creation
of the upgrade fails, then the following data is left in an inconsistent state:
> - Cluster Desired Version (still at 2.3)
> - Configurations: all new configurations created for 2.3 remain and are set as the desired
configuration.
> We need to cleanup this data so that a failure to begin the upgrade doesn't leave the
cluster in a bad state.
> STR:
> - Install HDP 2.2
> - Get ready to install HDP 2.3 by distributing the repo and resolving pre-req checks
> - Determine how you want to cause the failure. In my case, it was a problem while creating
all of the states and tasks in the database.
> - Try to upgrade; the upgrade will never get created, but all of the 2.3 configs will
and the desired states will change.
