Great work.
Code really looks cleaner
I left a couple of questions

| throw new RestException(Status.NOT_ACCEPTABLE, | ||
| "Number of partitions should be less than or equal to " + maxPartitions); | ||

this if statement was not present before, can it be null here ?

yes, I merged two methods which had duplicate code:
internalRemoveAutoTopicCreation and internalSetAutoSubscriptionCreation

| // (MetadataCacheImpl<ClusterData>) pulsar.getPulsarResources(). |
| if (ex.getCause() instanceof BadVersionException) { | ||
| // if resource is updated by other than metadata-cache then metadata-cache will get bad-version | ||
| // exception. so, try to invalidate the cache and try one more time. | ||
| objCache.synchronous().invalidate(key); |

This part is already in master, can you merge or rebase?

nit: ideally namespace resources should take a namespace name and internally resolve the path on metadata store.

yes, make sense. I will try to handle in another PR so, I can handle unit-test failures related to this change separately.

The exception and the log message seem to have diverged now
