Qin Liu commented on AMBARI-19829: ---------------------------------- @dsen & @atkach, Hi Dmytro and Andril, could you please review the fix? Thank you! > Several HDFS/YARN widgets on Heatmaps show N/A > ---------------------------------------------- > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
