------------------------------------
> AdminClient group operations may not respect backoff

> Key: KAFKA-9047
> URL: https://issues.apache.org/jira/browse/KAFKA-9047
> Project: Kafka
> Issue Type: Bug
> Components: admin
> Reporter: Jason Gustafson
> Assignee: Sanjana Kaundinya
> Priority: Major
> Fix For: 2.6.0
>
>
> The retry logic for consumer group operations in the admin client is
> complicated by the need to find the coordinator. Instead of simply retry
> loops which send the same request over and over, we can get more complex
> retry loops like the following:
> # Send FindCoordinator to B -> Coordinator is A
> # Send DescribeGroup to A -> NOT_COORDINATOR
> # Go back to 1
> Currently we construct a new Call object for each step in this loop, which
> means we lose some of retry bookkeeping such as the last retry time and the
> number of tries. This means it is possible to have tight retry loops which
> bounce between steps 1 and 2 and do not respect the retry backoff.
