-------------------------------------
Summary: ambari intermittently not able to detect the active NN
Key: AMBARI-14382
URL: https://issues.apache.org/jira/browse/AMBARI-14382
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.2.0
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Priority: Critical
Fix For: 2.2.1
Attachments: hdfs-HA.jpg
/main/services/HDFS/summary shows neither of the NN as active. This causes the
metrics to be wrong as they get data from the standby NN. This is an
intermittent issue where some times it shows the correct node as active and
some times it does not. However when it does show the correct node as active it
does not seem to pick up the metrics from that node.
