Description

GET app/v1/services/service-name/component-instances returns a list of containers with YARN-8299.

[
{
"id": "container_1531508836237_0001_01_000003",
"ip": "192.168.2.51",
"hostname": "HW12119.local",
"state": "READY",
"launch_time": 1531509014497,
"bare_host": "192.168.2.51",
"component_instance_name": "sleeper-1"
},
{
"id": "container_1531508836237_0001_01_000002",
"ip": "192.168.2.51",
"hostname": "HW12119.local",
"state": "READY",
"launch_time": 1531509013492,
"bare_host": "192.168.2.51",
"component_instance_name": "sleeper-0"
}
]

component_name is not part of container json, so it is hard to tell which component an instance belongs to.
To fix this, will change the format of returned containers to:

[
  {
    "name": "ping",
    "containers": [
      {
        "bare_host": "eyang-4.openstacklocal",
        "component_instance_name": "ping-0",
        "hostname": "ping-0.qqq.hbase.ycluster",
        "id": "container_1531765479645_0002_01_000002",
        "ip": "172.26.111.21",
        "launch_time": 1531767377301,
        "state": "READY"
      },
      {
        "bare_host": "eyang-4.openstacklocal",
        "component_instance_name": "ping-1",
        "hostname": "ping-1.qqq.hbase.ycluster",
        "id": "container_1531765479645_0002_01_000007",
        "ip": "172.26.111.21",
        "launch_time": 1531767410395,
        "state": "RUNNING_BUT_UNREADY"
      }
    ]
  },
  {
    "name": "sleep",
    "containers": [
      {
        "bare_host": "eyang-5.openstacklocal",
        "component_instance_name": "sleep-0",
        "hostname": "sleep-0.qqq.hbase.ycluster",
        "id": "container_1531765479645_0002_01_000004",
        "ip": "172.26.111.20",
        "launch_time": 1531767377710,
        "state": "READY"
      },
      {
        "bare_host": "eyang-4.openstacklocal",
        "component_instance_name": "sleep-1",
        "hostname": "sleep-1.qqq.hbase.ycluster",
        "id": "container_1531765479645_0002_01_000005",
        "ip": "172.26.111.21",
        "launch_time": 1531767378303,
        "state": "READY"
      }
    ]
  }
]
