Question

我使用raspberrypi构建hadoop集群，运行hdfs和yarn服务，使用Web ui观看NameNode master：50070可以连接，但是ResourceManager master：50070无法连接，我的配置是否错误？以下是我的文件

版本：3.1.2

yarn-site.xml：

 $.ajax({
        type: "POST",
        contentType: "application/json",
        url: "rest/user/login",
        data: JSON.stringify({"username": $("#username").val(), "password": $("#password").val()}),
        dataType: 'json',
        success: function (data) {
            var resultJson = JSON.stringify(data);
            $('#helloUserDiv').html(resultJson);
            console.log("SUCCESS : ", data);
            alert(data);
        },
        error: function (e) {
            var resultJson = e.responseText;
            $('#helloUserDiv').html(resultJson);
            console.log("ERROR : ", e);
        }
});
