> Key: AMBARI-19829
> URL: https://issues.apache.org/jira/browse/AMBARI-19829
> Project: Ambari
> Issue Type: Bug
> Components: ambari-metrics
> 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. YARN - 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.
