             Summary: Cyclic retry of ActionRequest in RaftGroupServiceImpl
                 Key: IGNITE-19095
                 URL: https://issues.apache.org/jira/browse/IGNITE-19095
             Project: Ignite
          Issue Type: Bug
            Reporter: Konstantin Orlov


Please take a look at the following snippet:

{code:java}
private void handleThrowable(
           ...
    ) {
        if (recoverable(err)) {
            ...

            scheduleRetry(() -> sendWithRetry(randomNode(peer), requestFactory, stopTime, fut));
        } else {
            fut.completeExceptionally(err);
        }
    }
{code}
In case of a recoverable error, the request will be sent once again. But if 2 out of 3 nodes had already been stopped, this retry logic will stuck in an infinite loop. The reason is that ConnectException is considered recoverable, and we are choosing another node keeping in mind only the node that had failed during current iteration.
