-------------------------------------
Summary: Rack Awareness does not work for Nodemanager only node
Key: AMBARI-18354
URL: https://issues.apache.org/jira/browse/AMBARI-18354
Project: Ambari
Issue Type: Bug
Reporter: Raghu Udiyar
The topology data is updated only for instances with DataNode component, and
not for NodeManager component. If we add compute only node with no HDFS, the
rack awareness does not get enabled for that node.
I see that the topology_mappings.data.j2 template
(https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/stacks/HDP/2.0.6/hooks/before-START/templates/topology_mappings.data.j2)
checks if the host is a `slave_host`. We should add NodeManager component
nodes in this list as well if appropriate, or add another check there.
