Проблема при запуске демонстрационного приложения Hazelcast

0 голосов
/ 07 октября 2019

Я новичок в сетке данных в памяти и Hazelcast. Я пробовал демонстрационное приложение на официальном веб-сайте.

https://training.hazelcast.com/demo-getting-started-with-hazelcast-imdg/277088/scorm/f2u8hre5zf9p

В нем упоминалось, что при многократном запуске приложения оно должно добавлять членов в один и тот же кластер.

Однако при повторном запуске программы кажется, что новый член не добавлен в тот же кластер.

Хотелось бы узнать, есть ли какие-либо возможные проблемы с моей настройкой, спасибо.

Окружающая среда:Eclipse IDEJDK 13Hazelcast 3.12.2

(Обновление от 8 октября 2019 г.)

Не совсем уверен, что произошло, но я смог получить ожидаемый результат после обновления до MacOS Catalina. Не уверен, относится ли это к ОС или нет.

Возможно, в вашей локальной среде установлено программное обеспечение для виртуализации? Возможно, многоадресный адрес по умолчанию в hazelcast конфликтует. Попробуйте изменить адрес на: 224.0.0.1:

cfg.getNetworkConfig (). GetJoin (). GetMulticastConfig (). SetMulticastGroup ("224.0.0.1");
