All the custom configuration and interpreters are lost after zeppelin restart

[#1]

Hi After performing a rolling upgrade from zeppelin 2.6.0 to 2.6.3, all the custom settings or interpreters are lost when zeppelin server is restarted.

[#2]

Hi, This is just to inform that the interpreter reset issue is resolved after upgrading the Ambari. I will recommend not to perform an HDP upgrade unless you have upgraded Ambari first.

[#3]

What do you mean by 'upgrading the Ambari'? We have installed 2.6.3 from scratch are experiencing exactly the same issue, this is: all Zeppelin notebook custom configurations are lost when you restart Zeppelin service.

Thanks.

If you are using Ambari 2.6.0, you can change "zeppelin.interpreter.config.upgrade" to "false" inside zeppelin's advance zeppelin config.

I'm experiencing the same results with HDP 2.6.3 and Ambari 2.5.2.0 - any changes to interpreter settings are lost when Zeppelin is restarted.

Hi Jon, I will suggest you to upgrade you Ambari to 2.6.0 and then you can change "zeppelin.interpreter.config.upgrade" to "false" inside zeppelin's advance zeppelin config. This parameter does not exist in the 2.5.2 Ambari and is included in the latest version.

@Sarfaraj Ahmad , @Jon Rollins, @Fernando Lopez Bello,

From HDP 2.6.3, Zeppelin supports storing notebooks and config in HDFS. The config is not actually lost but is stored in HDFS.

If "zeppelin.interpreter.config.upgrade" is set to true , then the configurations will be stored in /user/zeppelin/conf folder in HDFS and notebooks will be stored in /user/zeppelin/notebook.

You can check it by running.

hdfs dfs -cat /user/zeppelin/conf/interpreter.json
hdfs dfs -ls /user/zeppelin

If you are using Kerberos and still not able to see config changes in HDFS, add these 2 params in Custom zeppelin-config and restart zeppelin.

zeppelin.kerberos.enabled=true
zeppelin.server.kerberos.keytab=/etc/security/keytabs/zeppelin.server.kerberos.keytab

Thanks,

Aditya

Hi Aditya,

It is not the notebook which is getting lost, it is the interpreter settings and the new interpreters. This does not really get resolved by changing the settings as per your suggestion.

[#9]

I get this too. Very frustrating.

Any good answers yet?

I have this same problem. Very frustrating.

Anyone got a good answer yet?

Not yet. As of 2.6.4 I still see the issue.
