-------------------------------------------
Summary: Assign Slaves and Clients page displays incorrect
configuration unless a change is made in Assign Masters page
Key: AMBARI-20402
URL: https://issues.apache.org/jira/browse/AMBARI-20402
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.5.0
Reporter: Sangeeta Ravindran
Assignee: Sangeeta Ravindran
Attachments: AssignSlavesAndClients_AfterChanges.jpg,

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)
