Rohith Sharma K S updated YARN-7806:
------------------------------------
Description:
DS publishes container start/stop events using sync API. If back end is 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.
