[GitHub] zeppelin issue #1734: [ZEPPELIN-1766] Improve Interpreter Binding UI better ...

[AhyoungRyu]

Github user AhyoungRyu commented on the issue:

https://github.com/apache/zeppelin/pull/1734
  
@1ambda Great initiative for improving interpreter binding page UI! I also 
agree that current binding page is getting longer (thanks to the Zeppelin 
contributors :D) and getting hard to find. Definitely needs to be improved. I 
tested this branch and checked the improvement. Let me share my thought about 
this patch in here.

 - Currently the restart button is exposed so that ppl can know "I can 
restart this interpreter by clicking this button" by instinct. But \w this 
patch, ppl need to click "Carrot" button to open the dropdown menu and need to 
click "Restart" button to restart interpreter. And the user need to click at 
least one time to know about this. 

 - Seems don't need another tooltip in here since there is already the text 
"Restart"

 - The color change for default interpreter is good idea i think! But the 
color is gone when it comes out as a result.

 - Shirking overall size also good idea. Was quite verbose. But the thing 
that interpreter button has smaller height than dropdown menu is quite awkward 
to me.

 - How about "Search bindable interpreters(?)" instead of "Search 
interpreter Bindings"? :D

Most of them in the above are just my personal opinion. So surely you don't 
need to apply all of them. And thanks again for your effort to improve the UI!

 Summary: %spark is displayed twice in interpreter settings UI when 
%pyspark is made default
 Key: ZEPPELIN-1777
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1777
 Project: Zeppelin
  Issue Type: Bug
  Components: Core, GUI, Interpreters, pySpark
Affects Versions: 0.7.0
 Environment: Spark 2
Reporter: Ruslan Dautkhanov


%spark is displayed twice in interpreter settings UI when %pyspark is made 
default

When I made pySpark as default - it works as expected; 
except Setting UI. See screenshot below.

Notice it shows %spark twice.
First time as default. 2nd one is not.
It should have been %pyspark (default), %spark, ..
as I made pyspark default.

See screenshot.

Re: Export note as a PDF

[Ruslan Dautkhanov]

Thank you Hyunsung.

For various reasons we can't use Zeppelinhub.
One of the them being we have to run Zeppelin on-prem and don't depend on
any external resources.

I've created
https://issues.apache.org/jira/browse/ZEPPELIN-1774
"Export notebook as a pixel-perfect printable document, i.e. export as a
PDF"
Please vote up if you would find that useful too.

Thank you.

[jira] [Created] (ZEPPELIN-1775) Add dropdown item "Download Data as XLSX"

 Summary: Add dropdown item "Download Data as XLSX"
 Key: ZEPPELIN-1775
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1775
 Project: Zeppelin
  Issue Type: Improvement
  Components: Core, front-end, GUI
Affects Versions: 0.7.0
Reporter: Ruslan Dautkhanov


It's currently possible to download Data as CSV and TSV formats.

Please add dropdown item "Download Data as XLSX".

XLSX format has following advantages over CSV/TSV:
- it can carry also data types not just data;
- it can have compression built in;
- there is no csv import wizard to run - xlsx is self-descriptive.

XLSX format has several advantages over XLS:
- limits are 1,048,576 rows  (vs 65,536 in xls);
- 16,384 columns  (vs 256 in xls);
- main advantage is XLS is a proprietary binary format while XLSX is based on 
Office Open XML format.

Cloudera's Hue for example does allow do download query results as xlsx and our 
analysts find it very useful.

Export notebook as a pixel-perfect printable document, i.e. export as a PDF.

Any other wide-adopted format would do too, for example, I guess that could be 
Open Office XML format (.docx). Although PDF is preferred.

Our users are looking for functionality similar to Jupyter's save notebook as a 
PDF.

It would be great to have the same in Zeppelin.

GitHub user zjffdu opened a pull request:

https://github.com/apache/zeppelin/pull/1740

ZEPPELIN-1773. Remove method destroy() in Interpreter

### What is this PR for?
IMHO `destroy` is a little functional duplicated with `close`. And it seems 
currently only cassandra use destroy and it just calls `close()` 
https://github.com/apache/zeppelin/blob/master/cassandra/src/main/java/org/apache/zeppelin/cassandra/CassandraInterpreter.java#L231.
 So IMO, we could delete destroy method, also we can delete the destroy method 
in `InterpreterGroup`. 


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

### Todos
* [ ] - Task

### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-1773

### How should this be tested?
Just remove something so the existing test pass should be sufficient. 

### Screenshots (if appropriate)

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

[ZEPPELIN-572] pyspark interpreter doesn't work on yarn-client

### What is this PR for?
Set `spark.yarn.isPython` to be `true` to distribute pyspark libraries to 
workers when master is `yarn-client`

### What type of PR is it?
Bug Fix

### Is there a relevant Jira issue?
[ZEPPELIN-572](https://issues.apache.org/jira/browse/ZEPPELIN-572)

### How should this be tested?
You need yarn cluster to test this PR.
Simple way to test this PR would be running below code in paragraph and see 
if it throws error.
```
%pyspark
print(sc.parallelize([1, 2]).count())
```
And you should be able to see that `spark.yarn.isPython` is set to `true` 
in **Spark UI > Environment > Spark Properties** only when you set spark.master 
as `yarn-client`.

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

Hi Luciano

[jira] [Created] (ZEPPELIN-1772) Method to get current paragraph's ID in the paragraph

[Abhinav Sood (JIRA)]

Abhinav Sood created ZEPPELIN-1772:
--

 Summary: Method to get current paragraph's ID in the paragraph
 Key: ZEPPELIN-1772
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1772
 Project: Zeppelin
  Issue Type: New Feature
  Components: front-end, GUI, rest-api, zeppelin-interpreter
Reporter: Abhinav Sood


Provide a method like `getParagraphId()` to get the ID for the paragraph from 
which the method is called.

One of the use cases is having a paragraph that has a function that accepts 
input and generates the code to put D3.js visualizations in a DIV. It also 
accepts a paragraph ID as the input.

The function can be called from other paragraphs, and the D3js plot must be put 
into the DIV for that paragraph. With the `getParagraphId()` we can generate 
DIVs with IDs unique to the paragraph and not affect other paragraphs.

Re: Notebook example

[moon soo Lee]

Hi,

Appreciate for sharing a notebook and considering contribution.
You can contribute your note as a tutorial under
https://github.com/apache/zeppelin/tree/master/notebook by making
pullrequest. So Zeppelin distribution can include notebook. Just sharing on
the mailing list greatly helps as well if you prefer.

Don't hesitate making pullrequest or asking questions.

Thanks,
moon

Handling spark-submit errors

[Luciano Resende]

I was playing with some new data sources in Zeppelin (master) and had an
issue on my --package declaration in zeppelin-env.sh.

First, the error stack was a little misleading, as it was only reporting
connection issues to Spark trying to retrieve paragraph status.

>From my initial investigation, we pretty much invoke the spark-submit from
interpreter.sh... and I was wondering if there is a good way to trap this
kind of issues and be able to provide a better response to the user (or
even better logging)...

One option is to have something similar to what spark does, and actually,
have a class handling some of the interpreter integration logic.

Thoughts  ? Any other possibilities ?

@bzz @1ambda the script `start-zeppelin.sh` isn't important, it just 
enforce using port `8080` and zeppelin home dir `/usr/local/zeppelin`, we can 
ignore it and use `zeppelin.sh`.

@marchpig Sorry for my late response! I changed what you addressed except 
one thing.

### Korean note order

![image](https://cloud.githubusercontent.com/assets/8201019/21017141/b8b797e2-bdab-11e6-94db-7e1bac10389b.png)
### Remove date string when restore

![remove_date](https://cloud.githubusercontent.com/assets/8201019/21017265/16fa00d8-bdac-11e6-876f-c4c403f2192d.gif)

The one thing is about hiding `~Trash` prefix. I definitely agree with you 
but I think it's not good to make a PR huge. So if you think that feature is 
essential, I will include it to this PR. But if it's not, I would like to leave 
that as a future work :)

Actually, I planned to add features related to the trash on notebook view 
in the future. There are many features need to be implemented!
* Hide `~Trash` prefix
* Notice a note is in the trash
* Disable edit note in the trash (I'm not sure that this is needed, maybe 
limiting user's behavior)
* Disable renaming note in the trash (not sure as well)

The first and second features are needed in my opinion, so I would like to 
handle those on next PR!

Please tell me your opinion.
Thanks for the review again. It looks better than before thanks to your 
comments 😄

Notebook example

[Alexander Shoshin]

Hi everyone.

I want to become a Zeppelin contributor. Before starting to fix issues I 
decided to make an example of a notebook to become understand Zeppelin better 
:). I chose Apache Flink as a main Interpreter for my example because there are 
not so many examples of "Zeppelin on Flink" usage. I think it also may be 
helpful for your community according to 
https://issues.apache.org/jira/browse/ZEPPELIN-684, so here is the link: 
https://github.com/AlexanderShoshin/zeppelin-example

I am ready to make any kind of corrections in this example.

Alexander

[GitHub] zeppelin pull request #1733: [ZEPPELIN-1753] Fix blank notename issue

[marchpig]

GitHub user marchpig reopened a pull request:

https://github.com/apache/zeppelin/pull/1733

[ZEPPELIN-1753] Fix blank notename issue

### What is this PR for?
Note ID is displayed on action bar after pressing enter key with blank 
notename.
This is because the scope variable for notename is used directly as the 
model of input field and it doesn't revert the blank notename back to its 
existing name even though the notename was actually not updated to the blank 
value. (Temporarily lost notename from scope)
To resolve this issue, I added a variable to `ElasticInputCtrl` for the 
model of input field.
This change can always make the notename valid.

### What type of PR is it?
Bug Fix

### Todos

### What is the Jira issue?
https://issues.apache.org/jira/browse/ZEPPELIN-1753

### How should this be tested?
Input blank notename on action bar and..
- Check the notename on action bar
- Click 'Export this note' button and check the downloaded json filename.

### Screenshots (if appropriate)

[jira] [Created] (ZEPPELIN-1770) Restart only the client user's interpreter when restarting interpreter setting

[Jeff Zhang (JIRA)]

Jeff Zhang created ZEPPELIN-1770:


 Summary: Restart only the client user's interpreter when 
restarting interpreter setting
 Key: ZEPPELIN-1770
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1770
 Project: Zeppelin
  Issue Type: New Feature
Affects Versions: 0.7.0
Reporter: Jeff Zhang


ZEPPELIN-1306 implement the feature to restart the interpreter associated with 
the notes, this ticket is to implement to restart the interpreter associated 
with the user if user click to restart in the interpreter setting page.

Actually I think in future multiple user would be the major use case for 
zeppelin, so we should take user as the first dimension/parameter for any 
operation as opposed before we take noteId as the first dimension/parameter.
