---------------------------------------

Looks like this is true for job tracker jobs_submitted and jobs_completed also.

> In spite of the fact that some hadoop jobs that were performed, all fields of shuffle metrics have 0.0 values.
> Used the following request to get shuffle metrics:
> {code}
> api/v1/clusters/clusterName/hosts/hostName/host_components/TASKTRACKER?fields=metrics/mapred/shuffleOutput
> {code}
> Result:
> {code}
> "metrics" : {
> "mapred" : {
> "shuffleOutput" :
> { "shuffle_success_outputs" : 0, "shuffle_handler_busy_percent" : 0, "shuffle_output_bytes" : 0, "shuffle_failed_outputs" : 0, "shuffle_exceptions_caught" : 0 }
> }
> }
> {code}
