In the real-time stream, we have two coordinator node,

When the leader changes, the receiver nodes will retry the same error url until timeout.

 
{code:java}
private Object getRequest(String path) throws IOException {
    final String url = getBaseUrl() + path;
    CoordinatorResponse response = retryCaller.call(new CoordinatorRetryCallable() {
        @Override
        public CoordinatorResponse call() throws Exception {
            String msg = restService.getRequest(url);
            return JsonUtil.readValue(msg, CoordinatorResponse.class);
        }
    });
    return response.getData();
}
{code}
