Frühling Wolke Sidecar Lastausgleich versucht nicht auf Versagen

Ich habe folgendes Setup:Frühling Wolke Sidecar Lastausgleich versucht nicht auf Versagen

  • Frühling Wolke Eureka Server (Frühjahr Boot-App mit @EnableEurekaServer)
  • Frühling Wolke Sidecar (läuft auf :8080)
  • 2 Instanzen derselben Spring Boot-App ordnungsgemäß registriert gegen Eureka (@EnableEurekaClient) und einem einzigen GET /configurations Endpunkt ausgesetzt (läuft auf :8081 und :8082)

All dies läuft auf Java 8 + Spring Cloud 1.1.0.M5.

Das Aufrufen des REST-Endpunkts über Sidecar unter :8080 funktioniert einwandfrei, Anforderungen werden auf der Clientseite korrekt ausgeglichen und die Antworten sind korrekt. Wenn ich Abschaltung einer der 2 App-Instanzen und wieder den Endpunkt aufrufen, erhält der Kunde diesen Fehler:

{ 
    "timestamp": 1458328852272, 
    "status": 500, 
    "error": "Internal Server Error", 
    "exception": "com.netflix.zuul.exception.ZuulException", 
    "message": "Forwarding error" 
}

Die Sidecar-Protokolle zeigen:

Das Interessante daran ist, dass die Verbindung abgelehnt Fehler scheint erkannt zu werden (Stale connection detected) und ein Aufruf an die andere Instanz ist getan (ich sehe die eingehende Anfrage), aber das Ergebnis ist immer noch ein Fehler. Ich würde erwarten, dass die Antwort von dem Wiederholungsaufruf an den Client zurückgegeben wird.

Ist dies ein Meilenstein Fehler oder fehlt mir einige Konfiguration, um dies zu arbeiten?

Es ist wahrscheinlich die Wiederholung versuchen, aber insgesamt Hystrix oder Ribbon ist Zeitlimit. Der Standardwert ist sehr kurz. Es gibt einige Konfigurationsschlüssel, aber ich bin im Urlaub. Ping mich und ich werde sie nächste Woche finden. – spencergibb

Sie haben absolut Recht. Das Einstellen von hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 5000 löst das Problem. Vielen Dank! – Spiff

Es stellt sich heraus, dass Hystrix derjenige war, der das Zeitlimit überschritten hat. Die Einstellung hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 5000 scheint das Problem zu lösen.

Danke Spencer!
