> 1. On a multi-node cluster (for e.g. 5-node cluster), run the ambari install
> wizard.
> 2. Do not change defaults and navigate to Step 6 (Assign Slaves and Clients).
> 3. The recommended configuration does not seem to be place the components
> well. For e.g., DataNodes are recommended on all 5 nodes. (see
> AssignSlavesAndClients_BeforeChanges.jpg).
> 4. Navigate back to Step 5 (Assign Masters). Make a change. For e.g. move the
> Atlas Metadata Server to a different host. Next, change it back to the
> original host so that in effect nothing has changed.
> 5. Now move to Step 6 again and see that the configuration has changed and
> seems more in line with best practices although effectively nothing has
> changed in the Assign Masters page. (see
> AssignSlavesAndClients_AfterChanges.jpg)
