Subject [jira] [Updated] (YARN-6767) Timeline client won't be able to write when TimelineCollector is not up yet, or NM is down
Date Thu, 06 Jul 2017 16:54:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-6767?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Haibo Chen updated YARN-6767:
-----------------------------
    Description: 
As discussed in the call, when an application first starts to run, its corresponding TimelineCollector
instance may not be up yet, or if the TimelineCollector goes down when node manager dies (TimelineCollector
now runs as part of NM auxiliary services), the timeline client
will not able to write entities. We need to address or mitigate the issue if possible, or
at least call it out.
