Unable to access Zeppelin WEBUI after upgrade to 2.6.3 from 2.5.3

[#1]

I have upgraded HDP clsuter from 2.5.3 to 2.6.3 (not finalized at) in testing pahse.

Only zeppelin is the issue , rest all services are working fine. zeppelin webUI not able to access after upgrdae.

I have checked /usr/hdp/2.6.3.0-235/zeppelin/webapps

drwxr-x--- 3 zeppelin zeppelin 4096 Apr 23 14:13 webapps - permission , i have changed it to zeppelin:hadoop and restarted - again webapps folder ownership is chnaging to zeppelin:zeppelin bu service restart.

I tried to enable to HDFS storgae for zeppelin and tried with local as well by setting conf location and storage type. but still i am not able to access webui.

Kindly suggest

thanks in Adv

[#3]

when i restarted zeppelin notebook service via ambari, it's overwriting permission on /webapps directory with 750. may be this the reson i am not able ot access webUI. kindly suggest how can i stop zeppelin to stop overwrite permission and owner ship of the webappas directory under zeppelin installtion directory.

@Kant T

We see the error as following:

Load Interpreter Setting from file: hdfs://<NN>:8020/user/zeppelin/conf/interpreter.json 
WARN [2018-04-23 14:13:11,930] ({main} ContextHandler.java[log]:2062) - unavailable javax.servlet.ServletException: Resource class org.apache.zeppelin.server.ZeppelinServer can not be instantiated due to
 InvocationTargetException 
at org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet.createSingletonInstance(CXFNonSpringJaxrsServlet.java:396)

.

In general this can for the following reasons:

1. If the permission is not setup correctly on the Zeppelin webapp directory: (-R for recursive permission) zeppelin:hadoop permission is also good.

# chown -R zeppelin:hadoop /usr/hdp/2.6.3.0-235/zeppelin/webapps

2. If there are some corrupted notebooks under /usr/hdp/2.6.3.0-235/zeppelin/notebook Can you please check if there are any special/junk character inside any of the notebook which is making them corrupted. After taking a backup Deleting them can be a solution.

.

Thanks jay kumar,

performed below steps:

I have changed permission and owner on webapps folder and restarted the zeppelin, after restarted zeppelin via ambari ownership & permission are getting back old (owner - zeppelin:zeppelin & permission - 750).

Is there any conf or setting where can i make persistant ownership and permission on webappps directory.

please suggest

[#6]

@Kant T Is this same issue as the one described on https://community.hortonworks.com/questions/188846/zeppelin-web-page-http-error-503.html?childToView... ?

If yes, then please make sure that if the answer I provided on the above one helped you mark this one as well.

[#7]

Kant
