http://104.196.88.124:8080/api/v1/clusters/c1/services/YARN/components/RESOURCEMANAGER?fields=metrics/yarn/ClusterMetrics/NumActiveNMs._sum[1431372267,1431375867,15]&_=1431375867
{code}
Above is an API to return series data for number of active nodemanagers in the
asked time interval. Although the cluster has only 1 nodemanager installed, a
specific datapoint had 2 as a value which is incorrect.
*NOTE: Since there is only 1 nodemanager installed, the valid set of values at
any time is \{0,1\}.*
