After HDP 2.6.3 upgrade, I expect seeing Zeppelin starts updating its HDFS directory with new notes created since I was noticed in upgrade doc:
However, I don't see files or folders modified dates updated either new was created in HDFS.
I can't see any errors related to HDFS in Zeppelin log. HDFS log also does not contain any new lines for Zeppelin.
What I remember is I forgot copying notebook folder in HDFS in prerequisites step but did it after upgrade was completed. Then i restarted Zeppelin.
Do you have any idea about how I can make it write on HDFS?
Thanks in advance...

Is this a kerberized cluster?. Can you please check the below values.
1)zeppelin.notebook.storage is set to 'org.apache.zeppelin.notebook.repo.FileSystemNotebookRepo' in Advanced zeppelin-config
2) If it is a kerberized cluster then add these two configs in Custom zeppelin-config
zeppelin.server.kerberos.keytab= /etc/security/keytabs/zeppelin.server.kerberos.keytab (default)
zeppelin.server.kerberos.principal=zeppelin@REALM.COM (default)
3) Check if this folder exist in HDFS /user/zeppelin/notebook
Make these changes and restart zeppelin.

Hello @Aditya Sirna,
Thank you, it worked.
Cluster is not Kerberized.
1) Value was: "org.apache.zeppelin.notebook.repo.GitNotebookRepo,org.apache.zeppelin.notebook.repo.VFSNotebookRepo"
I have added also FileSystemNotebookRepo and after restart it updated the directory with the new notebook.
May this requirement be missing in upgrade documentation?

I am also getting a problem, i cannot save a notebook (HDP 2.6.5)
in the zeppelin ui i am getting:
"Couldn't checkpoint note revision: possibly storage doesn't support versioning. Please check the logs for more details."
in the log i get:
"WARN [2018-07-25 15:18:44,757] ({qtp1786364562-1678} FileSystemNotebookRepo.java[checkpoint]:159) - checkpoint is not implemented for HdfsNotebookRepo"
(not Kerberized)
can any one help?
