> PROBLEM: HDFS Heatmaps are not showing data (Not Applicable) for bytes read, bytes written
& DataNode Process Network I/O Utilization
> EXPECTED BEHAVIOUR: Heatmaps should show data
> ACTUAL BEHAVIOUR: Data is being shown as Not Applicable (Grey Box)
> ANALYSIS
>  This is reproducible in Ambari 2.2.2 and Ambari 2.5.1.0. If you go to HDFS, then click
on Heatmaps, you can see the API call go to 
> {code}
> fields=host_components/metrics/dfs/datanode/bytes_written._rate 
> {code}
> however this returns no values. If you remove ._rate then you can see the values which
you would expect.
