@Kant T Is your zeppelin configured to use remote storage for notebooks and interpreter settings? If so this is a known issue when upgrading to HDP 2.6.3 - The fix for this issue is already part of HDP 2.6.4. I understand there is a HDP internal bug and Hotfix you could request from Hortonworks Support if upgrading to 2.6.4 is not possible.

Here is the link to the tech alert sent not long ago about this problem, it contains steps on how to apply the hotfix as well:

Thanks for your comments

I am not using remote storage for notebook and interpreter. using local storage only.

my storage location is: /usr/hdp/2.6.xxxxxxx/zeppelin/notebook.

I manually changed permission and ownership as 755 & zeppelin:hadoop for webapps directory

my issues here is after restarting zeppelin service via ambri all permissions and ownership of the webapps follder will be changing

permissions are 750 - may be this the reason i am not able to access the webUI of zeppelin.

ownership - zeppelin:zeppelin

@Kant T

Have you tried using after changing the webapps directory user: group to zeppelin:hadoop and prevented Ambari from changing by using

# chattr -R +i /usr/hdp/2.6.3.x/zeppelin/webapps

Restart Zeppelin and relogin

[#10]

Thanks but No luck by changing attriubute as immuatable. after chnaging the attr log files saying that unable to delete temp webapps folder - warning.. actual my issue is not opening the zeppelin webpage at all.
