             Summary: Ambari alert "NameNode Last Checkpoint" failing when NameNode is HA
                 Key: AMBARI-17339
                 URL: https://issues.apache.org/jira/browse/AMBARI-17339
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.4.0


The "NameNode Last Checkpoint" alert is implemented in
_alert_checkpoint_time.py_. This script uses the value of **dfs.namenode.http-
address** property for querying the last checkpoint timestamp.

This works fine when the NN is not in HA mode. However when NN is in HA mode
this property is either not defined or might not be pointing to the right NN
instance.

The script needs to be improved such as to figure out if the NN is in HA mode.
If it's in HA mode do not use **dfs.namenode.http-address** property but
rather determine the correct URL to connect to similarly as how it's done in
the _alert_ha_namenode_health.py_
