>
> Looks like stackadvisor is used only upon a fresh install if no changes are
> made to the master components. In that case, the client/slaves are installed
> on all the hosts, so HAWQSEGMENT is co-located with DATANODE by default.
> If HDFS is already installed and HAWQ is enabled using add services, then
> Ambari chooses all hosts that do not have a MASTER component installed. This
> determination is being done in the javascript code.
> This patch is changing the hostlist for HAWQSEGMENT to be the same as
> DATANODE in the latter case.
