---------------------------------
Summary: Co-locate HAWQSEGMENT on hosts that have DATANODE
component
Key: AMBARI-14301
URL: https://issues.apache.org/jira/browse/AMBARI-14301
Project: Ambari
Issue Type: Improvement
Components: ambari-web
Affects Versions: trunk
Reporter: Lav Jain
Assignee: Lav Jain
Priority: Minor
Fix For: 2.3.0
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.
