> 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.
