             Summary: Stack Advisor Recommendation overrides installed slave components topology
                 Key: AMBARI-15589
                 URL: https://issues.apache.org/jira/browse/AMBARI-15589
             Project: Ambari
          Issue Type: Bug
          Components: stacks
            Reporter: Matt
            Assignee: Matt
             Fix For: 2.2.2


Stack Advisor recommendation overrides installed slaves topology of installed services when a new service is added.
Steps to reproduce:
- Install a cluster with HDFS and HAWQ select HAWQSEGMENTs on hosts different from the recommended set of hosts
- Install any other service (HBASE). Error: {color:red}On the assign slaves page, the HAWQSEGMENTs are checked according to recommendations and not according to the current host topology.{color}

The patch attached to this JIRA would fix the following issues:
- Recommendation given during Add Service wizard should be a combination of current topology for installed services and recommendation for service that is to be installed.
- Adding a new service after adding HAWQ or PXF would checkbox the HAWQSEGMENTs and PXFs correctly even if the user has placed these components different from the layout provided by the recommendation.
