> If the Ranger Admin is down then while starting any service from Ambari it
> keeps retrying 75 times in the interval of 8 seconds (total 600 Seconds ,
> Means 10 minutes) and then it finally starts the service like Kafka Broker
> service.
> Following kind of logging we can see in the ambari console when the Ranger
> Admin is Down and when the kafka broker start request is triggered (Attaching
> the "/var/lib/ambari-agent/data/output-297.txt" log):
> Snippet of the retry attempts:

> *What is Needed?*
> Here we see that it is not worth to wait for 600 Seconds (10 Minutes) to
> retry and then start the service (kafka broker Or any other component).
> Instead it can be reduced retry attempts to 15 times instead of trying 75
> times.
> *What was previous behavior?*
> Before the [AMBARI-14710|https://issues.apache.org/jira/browse/AMBARI-14710]
> the retry attempt was set to 15 times which was more accurate.
