> 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.
