Re: under what userid should Zeppelin run?

[moon soo Lee]

Hi Igor,

Zeppelin runs with user id that execute bin/zeppelin-daemon.sh or
bin/zeppeiln.sh. And all interpreter processes are running with the same
user id at the moment. So you'll need to change your user id to appropriate
one for your job and start Zeppelin.

In case of you're interested in impersonation, community is working on it
and you can track related issues
https://issues.apache.org/jira/browse/ZEPPELIN-1320
https://issues.apache.org/jira/browse/ZEPPELIN-1587
https://issues.apache.org/jira/browse/ZEPPELIN-1567
Hope this helps.

Thanks,
moon

Hi Moon,
So do I understand correctly that at the moment one cannot run a single 
Zeppelin server for all the users to connect to and each user is 
supposed to run his own instance of the server?
Zeppelin can use ldap for authentication so I thought that I can run it 
as root. But later I discovered that %sh would give root access to all 
the users!!!

Is there a way around it? Like running it under some service account?
With Jupyter, for example, there is JupyterHub that allows that: each 
user only has access to his account. Nothing like that for Zeppelin?

Thank you,
Igor

Re: under what userid should Zeppelin run?

[moon soo Lee]

Zeppelin already have three different modes for interpreter process
management.

 - shared : share a single process per note
 - scoped: share a single process but create instance inside per note
 - isolated : create a new process per note.

Now community also is actively working on bring this ability to not only
per note but also per user as well. Here's related issues. And i think
we'll have those features really soon.

I think you are referring impersonation. It is still in progress.

Here's one related ticket

Re: under what userid should Zeppelin run?

[Igor Yakushin]

Hi Moon,

This allows a user to specify who can see his note, right?

But that does not protect the system from users getting root access via 
%sh (or who knows what else) if Zeppelin is running as root?


Thank you,

Igor

Hi,

That's right. Until Zeppelin get impersonation implemented that i mentioned

Re: Graphics are not updated

[Balachandar R.A.]

Hi

Today I checked with my linux mozilla browser. No issue.However, my windows
firefox is still giving the same problem despite clearing the cache. I am
not convinced that this is an browser issue as you said, and that no issue
with the code or zeppelin.

Thanks

Hi Bala,

Thanks for sharing the problem.

Not sure but could you try newer version? zeppelin-0.6.2.
If it does not help, could you open developer console on your web browser
and see if there're any errors?

Thanks,
moon

Re: under what userid should Zeppelin run?

[Igor Yakushin]

Upon reading the documentation and coming with JupyterHub experience, it 
was natural to assume that Zeppelin should run as root, one daemon for 
all the users, especially considering that one can use it with ldap.


One should put it into the documentation with big red letters: *NEVER 
RUN ZEPPELIN AS ROOT !!!

*

Also, the daemon itself should check if it is running as root and die 
with violent complaints if yes. This is a major security problem.


This was not obvious at all to me that each user should run his own 
daemon on his account. I know at least one more place that made the same 
mistake as me and runs Zeppelin under root.

Also if I want to run all Zeppelin instances from one Linux machine, do I have 
to create the Zeppelin binaries for each user with different ports so that 
multiple instances can run in the same box?

405 method not allowed

[Vikash Kumar]

Hi all,
I am trying to convert the zeppelin-web application from Angular to Aurelia. 
When I am executing the following code  to get the interpreter binding I am 
getting error 405 method not allowed. Same error again in postman. I am able to 
hit the login api.

let url = BaseUrl.getRestApiBase() + '/notebook/interpreter/bind/' + 
this.note.id;
this.http.fetch(url, {
method: 'GET',
 headers: {
  'Content-Type': 'application/x-www-form-urlencoded'
}
  })
  .then(response => response.json())
  .then(data => {
console.log('Data === ', data);  //Empty
if((data || {}).status === 'OK') {
  this.interpreterBindings = data.body;
} else {
   console.log('Error %o %o', (data || {}).status, (data || 
{}).message);
}
  });

Thanks & Regards,
Vikash Kumar
