> YARN ATS Should Advertise a Version

> Key: AMBARI-16026
> URL: https://issues.apache.org/jira/browse/AMBARI-16026
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.0.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 2.4.0

> Attachments: AMBARI-16026.patch

> In YARN's {{metainfo.xml}}, ATS does not have a {{versionAdvertised}}
> element. As a result, the absence of this element causes Ambari to think that
> YARN is not part of the {{hdp-select}} logic and we will never validate that
> it is reporting the correct version on startup.
> However, YARN ATS does have a version and an entry in {{hdp-select}}:
> {code}
> if params.version and check_stack_feature(StackFeature.ROLLING_UPGRADE,
> params.version):
> conf_select.select(params.stack_name, "hadoop", params.version)
> stack_select.select("hadoop-yarn-timelineserver", params.version)
> {code}
> {code}
> [root@c6401 ~]# cat /usr/bin/hdp-select | grep "timeline"
> "hadoop-yarn-timelineserver": "hadoop-yarn",
> "hadoop-yarn-timelineserver"],
> {code}
> This actually causes the ATS component to say it has a {{VERSION_MISMATCH}}
> since upgrading HDP changes it's version when we were not expecting it to:
> {code}
> YARN_CLIENT 2.4.2.0-39 COMPLETE UNKNOWN
> APP_TIMELINE_SERVER 2.4.2.0-39 VERSION_MISMATCH UNSECURED
> ZOOKEEPER_SERVER 2.4.2.0-39 COMPLETE UNSECURED
> {code}
