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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
