Should we simply move the logic to set up the `ExponentialBackoff`in this function? I was thinking something like ```java private void reconfigureConnectorTasksWithRetry(long initialRequestTime, final String connName, ExponentialBackoff exponentialBackoff, int attempts) { ExponentialBackoff exponentialBackoff = new ExponentialBackoff( RECONFIGURE_CONNECTOR_TASKS_BACKOFF_INITIAL_MS, 2, RECONFIGURE_CONNECTOR_TASKS_BACKOFF_MAX_MS, 0); reconfigureConnectorTasksWithExpontialBackoff(initialRequestTime, connName, exponentialBackoff, attempts + 1); } ``` ########## connect/runtime/src/main/java/org/apache/kafka/connect/runtime/distributed/DistributedHerder.java: ########## @@ -1870,7 +1880,16 @@ private Callable<Void> getConnectorStoppingCallable(final String connectorName) }; } - private void reconfigureConnectorTasksWithRetry(long initialRequestTime, final String connName) { + /** + * Request task configs from the connector and write them to the config storage in case the configs are detected to + * have changed. This method retries infinitely in case of any errors. Review Comment: I am curious if there is a way to not do infinite retries. If we are actually retrying infinitely, esp in the case of `startConnector` phase, then the connector just doesn't have tasks. Is it possible to somehow bubble up errors as part of connector (not task) status? -- This is an automated message from the Apache Git Service.
