             Summary: Views: Jobs view support for existing ATS
                 Key: AMBARI-7035
                 URL: https://issues.apache.org/jira/browse/AMBARI-7035
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.7.0
            Reporter: Aleksandr Kovalenko
            Assignee: Aleksandr Kovalenko
            Priority: Critical
             Fix For: 1.7.0


Add an optional instance parameter so an AMBARI.ADMIN can configure the view to 
point to an existing / arbitrary ATS host and ResourceManager host.

{code}
<parameter>
    <name>yarn.ats.url</name>
    <description>The URL to the YARN Application Timeline Server, used to 
provide Jobs information, typically, this is the 
yarn.timeline-service.webapp.address property in the yarn-site.xml 
configuration. For example: http://yarn.ats.address:8188</description>
    <required>false</required>
</parameter>
  <parameter>
      <name>yarn.resourcemanager.url</name>
      <description>The URL to the YARN ResourceManager, used to provide YARN 
Application data. For example: 
http://yarn.resourcemanager.address:8088</description>
      <required>false</required>
  </parameter>
{code}

If these parameters are not set, the view should work as it does today (assumes 
ambari server hosting this view has the cluster to obtain ATS, and it gets that 
info from the Ambari REST API, and goes thru the ambari server proxy to 
retrieve info from ATS).

If these parameter are set, the view should just use this prop and the ambari 
server proxy to retrieve info from ATS).
