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