Upgrading Ambari Metrics

Steps

1. If Ambari Metrics service is not stopped, from Ambari Web, browse to Services > Ambari Metrics and select Stop from the Service Actions menu.
On every host in your cluster running a Metrics Monitor, run the following commands:
```
yum clean all
```
```
yum upgrade ambari-metrics-monitor ambari-metrics-hadoop-sink
```
Execute the following command on all hosts running the Metrics Collector:
