ignite.shスクリプトは何のために必要なのですか？

私は、単純なマルチノード計算の例を実行して起動しようとしています。私はバイナリのIgnite配布で提供されignite.shと3サーバーノードを実行したignite.shスクリプトは何のために必要なのですか？

try(Ignite ignite = Ignition.start("example-cache.xml")){ 
     IgniteCompute asyncCompute = ignite.compute().withAsync(); 
     for(int i = 0; i < 100; i++) { 
      int[] a = new int[1]; 
      a[0] = i; 
      asyncCompute.call(() -> { 
       out.println(a[0]); 
       return a[0]; 
      }); 
     } 
}

まず：私は、次の簡単なアプリケーションを書きました。それぞれ異なるJVMインスタンスにあります。

次に、私はこのアプリケーションをビルドし、前の3つのサーバーノードと同じxml-spring構成で実行します。

しかし、実際に、私は次の例外を得た：

この例外は完全に透明です。しかし、何のためにignite.shスクリプトが必要ですか？
