Qin Liu updated AMBARI-19829:
-----------------------------
Description:
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.
