Attachment: (was: AMBARI-8106_branch-1.7.0.patch)
> Ambari not showing HDFS Block status metrics of active namenode after a
> failover
> --------------------------------------------------------------------------------
>
> Key: AMBARI-8106
> URL: https://issues.apache.org/jira/browse/AMBARI-8106
> Project: Ambari
> Issue Type: Bug
> Components: ambari-web
> Affects Versions: 1.7.0
> Reporter: Andrii Tkach
> Assignee: Andrii Tkach
> Priority: Critical
> Fix For: 1.7.0
>
>
> PROBLEM:
> Ambari shows HDFS Block status metrics for NN1(active namenode). But when a
> failover happens to NN2, Ambari doesn't show the Block status metrics for
> NN2(current active namenode).
> BUSINESS IMPACT:
> Users not able to see the metrics via Ambari. They need to go to the Ganglia
> Web UI to monitor the metrics.
> STEPS TO REPRODUCE:
> 1. Currently NN1 is active. We are able to see the HDFS Block status metrics
> in Ambari
> 2. Failover to NN2.
> 3. We will not be able to see the Block status metrics for NN2.
> SUPPORT ANALYSIS:
> Support reproduced this issue in house.
