在我的測試環境中，我在intellij-project中獲得了1個點火節點，並且在運行二進制程序的Docker容器中的另一個節點點燃（通過ignite.sh）。分佈式緩存工作正常... 但我也想從我的點燃「主」節點控制點火節點。 首先，我只想打印「Hello World」，如下例所示： https://dzone.com/articles/getting-started-with-apache-ignite 但是，只有當我在同一個JVM中啓動另一個ignite-instance時，它纔會起作用。 如果我通過點燃二進制運行它，它不起作用。但它應該（如入門指南中所述...）Apache Ignite計算羣集
爲什麼節點搜索DockerExampleTest類？當然，它找不到，因爲ignite-binary的代碼和我的intellij-project的代碼是不同的...我只想要在節點上執行lambda表達式。
我的代碼：
Ignite ignite = Ignition.getOrStart(cfg);
ClusterGroup remoteGroup = ignite.cluster().forRemotes();
IgniteCompute compute = ignite.compute(remoteGroup);
compute.broadcast(() -> { System.out.println("Hello World"); });
錯誤：
