Subject [jira] [Created] (YARN-7806) DS will hang if ATSv2 back end is unavailable.
Date Wed, 24 Jan 2018 08:30:00 GMT
Rohith Sharma K S created YARN-7806:

             Summary: DS will hang if ATSv2 back end is unavailable. 
                 Key: YARN-7806
                 URL: https://issues.apache.org/jira/browse/YARN-7806
             Project: Hadoop YARN
          Issue Type: Bug
         Environment: DS publishes container start/stop events using sync API. If back end
is not down for some reasons, then DS will hang till container start/stop events are published.
By default, retry is 30 and interval is 1sec.

To publish single entity using sync API will take 1 minutes to come out. In case of DS, if
number of containers are 10 then 10minutes for start event and 10minutes for stop event. Overall
20 minutes will wait.


DS should publish container events using asyn api.
