Thomas Graves commented on MAPREDUCE-2863:
------------------------------------------
I updated the rest apis slightly. Here are the interfaces and will attach
output formats separately in a little while. Anyone interested in these please
review and comment.
Resource Manager:
http://host:8088/ws/v1/cluster/info
http://host:8088/ws/v1/cluster/nodes -> query params: state(String of
RMNodeState) and healthy(boolean)
http://host:8088/ws/v1/cluster/nodes/{nodeAddress} -> nodeAddress is host:port
format
http://host:8088/ws/v1/cluster/metrics
http://host:8088/ws/v1/cluster/metrics/{user}
http://host:8088/ws/v1/cluster/scheduler
http://host:8088/ws/v1/cluster/apps/{appid}
http://host:8088/ws/v1/cluster/apps -> query params: state(String of
RMAppState), user(String), queue(String), limit(int of number to return),
startTimeBegin(ms since epoch), startTimeEnd(ms since epoch),
finishTimeBegin(ms since epoch), finishTimeEnd(ms since epoch)
Node Manager:
http://host:9999/ws/v1/nodes/info
http://host:9999/ws/v1/nodes/apps -> query params: state(String of
ApplicationState), user(String)
http://host:9999/ws/v1/nodes/apps/{appid}
http://host:9999/ws/v1/nodes/containers
http://host:9999/ws/v1/nodes/containers/{containerid}
mapreduce Application Master - these go through the proxy just like web ui
http://host:8088/proxy/{appid}/ws/v1/mapreduce/info
http://host:8088/proxy/{appid}/ws/v1/mapreduce/jobs
http://host:8088/proxy/{appid}/ws/v1/mapreduce/jobs/{jobid}

http://host:8088/proxy/{appid}/ws/v1/mapreduce/jobs/{jobid}/conf
http://host:8088/proxy/{appid}/ws/v1/mapreduce/jobs/{jobid}/tasks -> query
params: type(m or r)
http://host:8088/proxy/{appid}/ws/v1/mapreduce/jobs/{jobid}/tasks/{taskid}
http://host:8088/proxy/{appid}/ws/v1/mapreduce/jobs/{jobid}/tasks/{taskid}/attempts
http://host:8088/proxy/{appid}/ws/v1/mapreduce/jobs/{jobid}/tasks/{taskid}/attempts/{attemptid}
History Server:
http://host:19888/ws/v1/history/info
http://host:19888/ws/v1/history/mapreduce/jobs -> query params: user(String),
limit(int of # to return), startTimeBegin(ms since epoch), startTimeEnd(ms
since epoch), finishTimeBegin(ms since epoch), finishTimeEnd(ms since epoch),
queue(String)
http://host:19888/ws/v1/history/mapreduce/jobs/{jobid}
http://host:19888/ws/v1/history/mapreduce/jobs/{jobid}/counters
http://host:19888/ws/v1/history/mapreduce/jobs/{jobid}/counters/{group}/{counterName}
http://host:19888/ws/v1/history/mapreduce/jobs/{jobid}/tasks/{taskid}/counters

For reference:
public enum ApplicationState {
NEW, INITING, RUNNING, FINISHING_CONTAINERS_WAIT,
APPLICATION_RESOURCES_CLEANINGUP, FINISHED
}
public enum RMNodeState {
RUNNING, UNHEALTHY, DECOMMISSIONED, LOST
}
public enum RMAppState {
NEW, SUBMITTED, ACCEPTED, RUNNING, FINISHED, FAILED, KILLED
}
