>
> 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_
