> 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.
