Why Is an Alarm Generated When the NameNode Process Is Not Restarted After the hdfs-site.xml File Is Modified?

If you do not restart the NameNode process after modifying the dfs.namenode.checkpoint.period parameter, an alarm may be falsely reported. In this case, you need to restart the NameNode process as soon as possible.
