hadoop - 如何从Yarn rest API在浏览器上获取JSON？

Question

我想从hadoop资源管理器中获取所有工作，所以我尝试了yarn rest API，但这在浏览器中返回了XML，因此有什么方法可以从其中获取JSON？

我点击的网址如下:
服务器:端口/ ws / v1 /群集/应用

正如Mr Srinivas先生所建议的，Accept:Application / json会做您想要的事情。这是一个例子:

Seans-MacBook-Pro:~% wget -qO- --header="Accept: Application/json" http://amarillo-rm.pepperdata.com:8088/ws/v1/cluster/info


{
  "clusterInfo": {
    "id": 1479097299577,
    "startedOn": 1479097299577,
    "state": "STARTED",
    "haState": "ACTIVE",
    "rmStateStoreName": "org.apache.hadoop.yarn.server.resourcemanager.recovery.NullRMStateStore",
    "resourceManagerVersion": "2.6.0-cdh5.5.1",
