Examples of ClusterMetrics

org.apache.hadoop.mapreduce.ClusterMetrics
Status information on the current state of the Map-Reduce cluster.
ClusterMetrics provides clients with information such as:
1. Size of the cluster.
2. Number of blacklisted and decommissioned trackers.
3. Slot capacity of the cluster.
4. The number of currently occupied/reserved map & reduce slots.
5. The number of currently running map & reduce tasks.
6. The number of job submissions.
