Re: Google OAuth in Zeppelin

[Khalid Huseynov]

Actually simple implementation for OpenId was done in
https://github.com/apache/zeppelin/pull/2373 through shiro using buji-pac4j
library as you said. This library provides integration realm for OAuth as
well, so I think good starting point would be to configure buji-pac4j with
OAuth realm, and theoretically it should be working or may need some
modifications to already existing flow.

https://github.com/apache/zeppelin/pull/2471
  
Yes, that's what it is doing now (in the case of Phoenix SQL) it gives a 
valid result with error stack trace, and paragraph results in error. Hence, I 
thought we could either choose to improve it or leave it.

### What is the Jira issue?
[ZEPPELIN-2593](https://issues.apache.org/jira/browse/ZEPPELIN-2593)

### How should this be tested?
1. go to notebook repo menu and click on edit `Global settings` or do 
through env var `ZEPPELIN_NOTEBOOK_PERSISTENCE`
2. change value of `Note persistence` item to `Persist on note run and 
commits` or change value of `ZEPPELIN_NOTEBOOK_PERSISTENCE` into "run"
3. go change any note, although it will be changed in memory, it won't be

Re: Google OAuth in Zeppelin

[Jongyoul Lee]

Hi,

AFAIK, we have talked about OAuth, but didn't decide anything including how
to implement it and how to support it. We are using shiro for
authentication. Do you have any idea to support OAuth using Shiro?

Re: [DISCUSS] Reducing default interpreters while building and releasing Zeppelin

[Jongyoul Lee]

Hi,

I think it's time to move to the next step. Zeppelin's web site is already
changed. Zeppelin's default package also provide same interpreters and
include markdown and shell. How do you think of it?

Regards,
Jongyoul

https://github.com/apache/zeppelin/pull/2474

[ZEPPELIN-2753] Basic Implementation of IPython Interpreter

### What is this PR for?
This is the first step for implement IPython Interpreter in Zeppelin.  I 
just use the jupyter_client to create and manage the ipython kernel. We don't 
need to care about python compilation and execution, all the things are 
delegated to ipython kernel. Ideally all the features of ipython should be 
available in Zeppelin as well.  

### What type of PR is it?
[Feature ]

### Todos
* [ ] - Task

### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-2753

### How should this be tested?
Unit is added. 

### Screenshots (if appropriate)
Verify bokeh in IPython Interpreter

### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No

To reproduce:

1- Create a Spark notebook with ``exit`` as content
2- Run notebook, Spark should disconnect interpreter
3- Try restart Spark interpreter -> NullPointer exception (must restart 
Zeppelin)

[GitHub] zeppelin pull request #2472: [ZEPPELIN-2749] Use scalable file structure for...

[ZEPPELIN-2749] Use scalable file structure for zeppelin web

### What is this PR for?

We have improved zeppelin-web, but some parts are still messy. As part of 
keeping zeppelin-web module healthy 
([ZEPPELIN-2725](https://issues.apache.org/jira/browse/ZEPPELIN-2725)), I 
suggest having these file structure. (Refer the screenshot section)

Here are few reasons.

- unified directory, file name helps us to recognize, find which part we 
should modify / fix
- [this 
structure](https://github.com/toddmotto/angularjs-styleguide#file-naming-conventions)
 is what the angularjs community has verified for few years. so newly joined 
developers can feel more comfortable.
- this is necessary for [Modular 
archiecture](https://issues.apache.org/jira/browse/ZEPPELIN-2750) and it 
eventually helps us to make a smooth transition toward next technologies (even 
whatever we will use)

Additionally, 

- This is not the meaningless refactoring PR and doesn't block developing 
new features / fixes (Please refer the `Some Details` section)
- I will handle conflicts for few days would be brought by other WIPs

 How to Review This PR?

 Some Details

- Didn't change the widely used variable names not to make many conflicts. 
For example, `websocketMsgSrv`, `arrayOrderingSrv`
- Since there are helium packages already published, didn't changed the 
html names like `pivot_setting.html` (it's better to use `pivot-setting.html` 
if we following the rule)
