>                 Key: AMBARI-19829
>                 URL:
>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.2.2
>            Reporter: Qin Liu
>            Assignee: Qin Liu
>             Fix For: trunk
>         Attachments: AMBARI-19829.patch
> The following HDFS/YARN widgets on Heatmaps show N/A:
> 1. HDFS - HDFS Bytes Written, HDFS Bytes Read, DataNode Process Disk I/O Utilization,
and DataNode Process Network I/O Utilization
> 2. YANR - Container Failures
> The issue was introduced by AMBARI-15835 "Rate metrics requesting widgets do not show
up on Ambari" which introduced rate metrics and applied rate metrics to several HBASE/HDFS/YARN
widgets on Summary pages  as well as Heatmap pages. Rate metrics work fine on Summary pages
but they don't work on Heatmap pages because current Heatmap design can only show point-in-time
metrics and rate metrics need a time range.
