Chandni Singh updated YARN-8542:
--------------------------------
Description:
GET app/v1/services/{\{service-name}}/component-instances returns a list of
containers with YARN-8299.
{code:java}
[
{
"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"
}
]{code}
{{component_name}} is not part of container json, so it is hard to tell which
component an instance belongs to.
was:
In YARN-8299, CLI for query container status is implemented to display
containers in a flat list. It might be helpful to display component structure
hierarchy like this:
