Description

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:

api/v1/clusters/clusterName/hosts/hostName/host_components/TASKTRACKER?fields=metrics/mapred/shuffleOutput

Result:

"metrics" : {
"mapred" : {
"shuffleOutput" :
{ "shuffle_success_outputs" : 0, "shuffle_handler_busy_percent" : 0, "shuffle_output_bytes" : 0, "shuffle_failed_outputs" : 0, "shuffle_exceptions_caught" : 0 }

}
}
