[GitHub] zeppelin issue #2372: [ZEPPELIN-2581] Shell ansi codes

[DrIgor]

Github user DrIgor commented on the issue:

https://github.com/apache/zeppelin/pull/2372
  
I am not sure If themes should be shell interpreter feature. Maybe we can 
provide themes for every interpreter's text output?

highlight.js should be used for input, not output. Output already contains 
information about colors and text styles

@felixcheung Thanks for the feedback.
Not sure if i got your question.
I will try to elaborate more on the change
The userinfo will give a picture of what is run/being run by whom  and its 
duration, in the spark application.(Currently, we display **zeppelin**)
The spark web UI will list all jobs, with this user information.

[ZEPPELIN-1906] Use multiple InterpreterResult for displaying multiple JDBC 
queries

### What is this PR for?
Use multiple InterpreterResult for displaying multiple JDBC queries.
IMO since other sql editors allows to execute multiple sql separated with 
";" and ours display mechanism being more powerful, hence, it should also allow 
the same.

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

### What is the Jira issue?
* [ZEPPELIN-1906](https://issues.apache.org/jira/browse/ZEPPELIN-1906)

### How should this be tested?
Try running following in a paragraph (with Postgres setting) and check for 
output.

```
%jdbc
create table test_temp_table (id int);
select column_name, data_type, character_maximum_length from 
INFORMATION_SCHEMA.COLUMNS where table_name = 'test_temp_table';
SELECT table_name FROM information_schema.tables WHERE table_schema = 
'public';
drop table test_temp_table;
SELECT table_name FROM information_schema.tables WHERE table_schema = 
'public';
```

### Screenshots (if appropriate)

### Questions:
* Does the licenses files need update? N/A
* Is there breaking changes for older versions? N/A
* Does this needs documentation? N/A

GitHub user 1ambda opened a pull request:

https://github.com/apache/zeppelin/pull/2375

[ZEPPELIN-2527] Use thin (normal) cursor.

### What is this PR for?

Previously, it's hard to recognize where (**before or after**) the cursor 
is since it's too thick.

See the attached GIFs for comparison.

These key bindings are still supported in the default mode. 

- `CTRL + P`, `CTRL+N`: go to next / previous line
- `CTRL + F`, `CTRL+B`: go to next / previous letter
- `CTRL + A`, `CTRL+E`: go to the beginning / end of the line

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

### Todos
* [x] - Use default mode instead of emacs
* [x] - Bind `CTRL + P` for OSX.

### What is the Jira issue?

[ZEPPELIN-2527](https://issues.apache.org/jira/browse/ZEPPELIN-2527)

### How should this be tested?

1. Build: `mvn clean package -DskipTests;`
2. Open a paragraph.
2. Check the cursor

[Felix Cheung]

Seems to be with hdfs ACL - does the service user Zeppelin have access to your

Subject: Permission denied: user=zeppelin while using %spark.pyspark 
interpreter in AWS EMR cluster

Hi Team,

I have created pyspark structure streaming program and trying to execute in
the Zeppelin notebook, I am getting the following error:

Py4JJavaError: An error occurred while calling o191.start.
: org.apache.hadoop.security.AccessControlException: Permission denied:

I am using Zeppelin Notebook Version 0.7.1 in AWS EMR cluster.

Help would be much appreciated.

Cool!
I'd love the dark theme, but I don't think we should force this onto users?

 Summary: Securing Zeppelin with OpenID Connect
 Key: ZEPPELIN-2598
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2598
 Project: Zeppelin
  Issue Type: Improvement
Reporter: Andrea Peruffo
Priority: Minor


We want to enable user to login to all applications on the cluster using the 
same mechanism.
In this case OpenID Connect is the choice and it plugs (almost) smoothly with 
shiro thanks to Pac4J project.
This will also open the road to other authentication mechanisms to be plugged 
in.

Hi @sven0726, Thanks for the contribution. I added a comment. 

- This pr is not related with CI, but if you want to modify code you need
