Symptoms

After upgrade to BDA V4.3 NodeManagers (NM) are added on NameNodes (NN) on clusters greater than 6 nodes. This is noticed when bdacheckcluster reports that NMs are not running on the NNs like:

On 6 node Starter Racks NMs run on all nodes of the cluster, otherwise NMs do not run on the NNs.  In clusters 8 nodes and greater NodeManagers should therefore not be running
the NameNodes.
