If this error is somewhat related to the other thread that you posted recently: https://community.hortonworks.com/questions/168750/ambari-cluster-no-valid-image-files-found.html?ch...

Then please apply the same solution and close one of the thread.

Pasting the steps here:

Please check if the dfs.namenode.name.dir (default path: /hadoop/hdfs/namenode) directory is empty by any chance, due to disk issue the files are not present there.

If this is the case and the Active NameNode is already running (this must be true) then you can try the following:

Try running the following command:

# su - hdfs 
# hdfs namenode -bootstrapStandby <br>

NOTE: Please run this command ONLY on Standby NameNode. DO NOT run this command on Active NameNode. This command will try to recover all metadata on Standby NameNode.
.

- Now try to start Standby NameNode from Ambari
- Also please Restart ZKFailoverController from Ambari

.
