[bzz]

Github user bzz commented on the issue:

https://github.com/apache/zeppelin/pull/932
  
A quick search over JIRA suggests that the failure you reffer was taked 
care of in [ZEPPELIN-1264](https://issues.apache.org/jira/browse/ZEPPELIN-1264) 
and is resolved in latest master, please rebase.


In PR body 

> Does the licenses files need update? N

I think it does

@echarles all transitive dependencies lie `woodstox` and 
`org.glassfish.jersey.bundles` and `javax.validation`, etc  will be included in 
convenience binary for release so each of them must be as well included in 
`zeppelin-distribution/src/bin-license/LICENSE` according to their license. 
Could you please double check that?



>Jersey2 can better manage the JSON bodies and mappings.

Could you please elaborate on that part? People might not be very familiar 
with it very well, so if you could put the benefits of such change in PR 
description - that would help a lot.

Thank you!

ZEPPELIN-1270. Remove getting SQLContext from SparkSession.wrapped()

### What is this PR for?
SparkSession.wrapped is only for spark 2.0 preview, it is not supported in 
spark 2.0 release. So I think we can remove that piece of code. Otherwise we 
will get the following error in log which might be a little confusing.
```

[AhyoungRyu]

GitHub user AhyoungRyu opened a pull request:

https://github.com/apache/zeppelin/pull/1266

[ZEPPELIN-1219] Add searching feature to Zeppelin docs site

### What is this PR for?
As more and more document pages are added, it's really hard to find 
specific pages. So I added searching feature to Zeppelin documentation 
site([jekyll](https://jekyllrb.com/) based site) using 
[lunr.js](http://lunrjs.com/).

 - **How it works?**
  
  I created 
[`search_data.json`](https://github.com/AhyoungRyu/zeppelin/blob/6e02423f541cc406e4e41031629609a276a9f481/docs/search_data.json)
 which is used for docs info template. `lunr.js` combines all of the text from 
all of the docs in `docs/` into `_site/search_data.json`. It looks like below.
![screen shot 2016-08-03 at 4 49 59 
am](https://cloud.githubusercontent.com/assets/10060731/17342828/f2908be8-5935-11e6-8eee-b189677c0531.png)
All the info are comes from [Jekyll YAML front 
matter](https://jekyllrb.com/docs/frontmatter/) variables. (i.e. title, group, 
description.. that's why I rewrote all docs' title and description.)
Using this data, 
[search.js](https://github.com/AhyoungRyu/zeppelin/blob/6e02423f541cc406e4e41031629609a276a9f481/docs/assets/themes/zeppelin/js/search.js)
 will do this job!

### What type of PR is it?
Improvement & Feature

### Todos
* [x] - Keep consistency for all docs pages' `Title`
* [x] - Add some overview sentences to all docs pages' `Description` 
section (this will be used as the result preview)
* [x] - Add apache license header to all docs page (some pages are missing 
the license header currently)
* [x] - Add LICENSE for `lunr.min.js`

### What is the Jira issue?
[ZEPPELIN-1219](https://issues.apache.org/jira/browse/ZEPPELIN-1219)

### How should this be tested?
1. Build docs site -> please see 
[docs/README.md#build-documentation](https://github.com/apache/zeppelin/tree/master/docs#build-documentation)
2. Click `search` icon in navbar and go to `search.html` page
3. Type anything you want to search in the search bar (i.e. type `python`, 
`spark`, `dynamic` ... )

### Screenshots (if appropriate)
https://cloud.githubusercontent.com/assets/10060731/17343202/71185300-5937-11e6-9e57-687bf2839cfb.png;>

### Questions:
* Does the licenses files need update? Yes, for `lunr.min.js`
* Is there breaking changes for older versions? no
* Does this needs documentation? no

@minahlee Just saw you comment on ZEPPELIN-1260, but @Leemoonsoo has been 
fast...

I have tested the changes, and now sparkr dataframes are working well (with 
the `spark` variable which referts to the new Spark2 session).

The R tutorial note refers to sqlContext which is no more present

```
Error in dispatchFunc("createDataFrame(data, schema = NULL, samplingRatio = 
1.0)", : object 'sqlContext' not found
```

Patch could also expose sqlContext.

`setParagraphMode`, the conditions you added is already at the beginning of the 
function.

`$scope.setParagraphMode` can also be changed to `var setParagraphMode`

Some unittest launches remote interpreter process for the test with some 
mock interpreter implementation. So mock interpreter class in the test should 
be available for interpreter's classpath for the test.

[GitHub] zeppelin issue #1231: [Zeppelin - 683][WIP] BittorrentNotebookRepo

[onkarshedge]

Github user onkarshedge commented on the issue:

https://github.com/apache/zeppelin/pull/1231
  
@bzz . I will post a diagram of communication for clear view.
`BittorrentNotebookRepo` does not implement/override any `NotebookRepo` 
methods. It uses all VFSNotebookRepo methods.
```java
Note get(String noteId, AuthenticationInfo subject);
List list(AuthenticationInfo subject);
void save(Note note, AuthenticationInfo subject);
```
Only two key methods are
```java
public String shareNote(String noteId); // take the note.json file and 
start seeding, return magnet link
public void download(String magnetLink); // download the files in the 
torrent directory.
```

```
Initial idea the we discussed was that BittorrentNotebookRepo encapsulates 
all the things that are required in order to get notebooks.
```
Could you please elaborate this point. 
Once the design and goal is clear, it will help me implement faster. 
Give me some time I will post a diagram..

@onkarshedge on the architecture side - could you please elaborate on the 
design that you choose, especially regarding `TorrentServlet` - why do you need 
a new servlet? What are the parts that communicate to each other? A diagram 
(event ASCI one) would help here.

On the code side - please read the project style guide for Java language 
carefully and make sure you follow the conventions described there.

[GitHub] zeppelin issue #1231: [Zeppelin - 683][WIP] BittorrentNotebookRepo

[onkarshedge]

Github user onkarshedge commented on the issue:

https://github.com/apache/zeppelin/pull/1231
  
@khalidhuseynov  thanks for helping.

To actually see `TorrentSocket` in action I have to create 
a`WebSocketCreator` and a `Servlet`, then add this to jetty server , [at this 
line](https://github.com/apache/zeppelin/blob/6f867ceb0c2b93ecca3be8a16c155547182eb0dc/zeppelin-server/src/main/java/org/apache/zeppelin/server/ZeppelinServer.java#L223)
```java
webApp.addServlet(new ServletHolder("ws-events",new 
TorrentServlet()),"/download");
```
So then should it be like this ...
```java
public class BittorrentNotebookRepo extends VFSNotebookRepo implements 
TorrentEngineListener,
WebSocketCreator {
@Override
public Object createWebSocket(ServletUpgradeRequest servletUpgradeRequest,
 ServletUpgradeResponse servletUpgradeResponse) {
return new TorrentSocket(this);
  }
}
```
And the `TorrentServlet` class
```java
public class TorrentServlet extends WebSocketServlet {
  @Override
  public void configure(WebSocketServletFactory webSocketServletFactory) {
webSocketServletFactory.setCreator(new BittorrentNotebookRepo());
  }
}
```
Here is the problem as I cannot instantiate the BittorrentNotebookRepo here 
, it requires `conf` parameter. Also the NotebookRepos' are instantiated in 
`NotebookRepoSync`.

[jira] [Created] (ZEPPELIN-1268) As an enduser, I would like to embed paragraph and refresh the content of it in my custom UI

[Kavin Kumar (JIRA)]

Kavin Kumar created ZEPPELIN-1268:
-

 Summary: As an enduser, I would like to embed paragraph and 
refresh the content of it in my custom UI
 Key: ZEPPELIN-1268
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1268
 Project: Zeppelin
  Issue Type: Improvement
  Components: front-end, zeppelin-server, zeppelin-zengine
Reporter: Kavin Kumar


Being an end user of Apache Zeppelin, I would like to add the following 
enhancements to the codebase so that I can embed paragraph and also refresh the 
paragraph content from the custom UI.Note that the custom UI is different from 
the notebook UI and served by a simple js application.Embedding the paragraph 
content and refreshing the content of it in the custom UI are done using the 
Zeppelin REST APIs.

When we analyzed the existing APIs and the notebook UI, we thought that the 
following would be helpful when someone wants to do the same as mentioned above:

* Expose paragraph id as a new option for each paragraph in the notebook UI say 
"Get the paragraph id" so that the end user can easily find it out
* Create a new REST API to find out the status of a single paragraph

https://github.com/apache/zeppelin/pull/1260

ZEPPELIN-1267. PySparkInterpreter doesn't work in spark 2.0

### What is this PR for?
PySparkInterpreter doesn't work in spark 2.0 because pyspark and py4j is 
not distributed to executors.  This PR extract the setup staff for pyspark 
interpreter into method setupConfForPySpark and use it for both spark1 and 
spark2. But this is just a short term solution, as I think this should be 
handled by spark rather than zeppelin, here zeppelin duplicate part of spark's 
work. In the long term, I'd like to resolve it in `ZEPPELIN-1263`.


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

### Todos

### Screenshots (if appropriate)

* Is there breaking changes for older versions? No
* Does this needs documentation? No

Thanks @minahlee, it works. But any reason to make it hidden by default ? 
But it is not intuitive for me that I can click the gear button to display it.

Do you mean by modifying the UI on notebook creation or using a param to 
selecting the interpreter like
 '%livy --jars [path]

@onkarshedge thanks for this contribution. as i can see, the design issue 
on passing `BittorrentNotebookRepo` to `TorrentSocket` was solved by passing 
through constructor. also better have torrent websocket message handling 
separate from `NotebookServer` as you did. any other design issues left 
non-mentioned?

[jira] [Created] (ZEPPELIN-1265) Value of zeppelin.pyspark.python not reflected the python version Spark executors use on YARN

[Sami Jaktholm (JIRA)]

Sami Jaktholm created ZEPPELIN-1265:
---

 Summary: Value of zeppelin.pyspark.python not reflected the python 
version Spark executors use on YARN
 Key: ZEPPELIN-1265
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1265
 Project: Zeppelin
  Issue Type: Bug
Affects Versions: 0.5.6
Reporter: Sami Jaktholm


STR:
0. Have both python2 and python3 installed
1. Set {{zeppelin.pyspark.python}} to {{python3}} (or where your Python 3 is 
installed)
2. Run some pyspark code that involves executing tasks on executor nodes

What happens:
bq. Exception: Python in worker has different version 3.4 than that in driver 
2.7, PySpark cannot run with different minor versions

What should happen: The code runs without exceptions as the value of 
{{zeppelin.pyspark.python}} is correctly propagated to the Spark executors. IMO 
the correct behavior is to use the the value {{zeppelin.pyspark.python}} as the 
Python interpreter with Spark and set {{PYSPARK_PYTHON}} to that same value so 
that Spark can pick it up and ship it to executors.

The problem here is that when {{zeppelin.pyspark.python}} is set to use Python 
3, Zeppelin starts the Spark master process with python3. However, this 
configuration is not reflected on the executors and they use what they can find 
in {{PYSPARK_PYTHON}} envvar, which defaults to Python 2. So changing python 
version also requires setting {{PYSPARK_PYTHON}} to correct value which it not 
easy thing to do on the fly (I guess you need to change a config file somewhere 
and restart Zeppelin to achieve that).

This might only be an issue when running Spark on a YARN cluster with multiple 
machines (as in the selection of python version is not propagated to the 
executor machines) since I haven't tested this in a single machine scenario. 
Also, I haven't been able to test this in Zeppelin 0.6.0 yet so this could 
already be fixed but I didn't find any similar tickets that were resolved after 
Zeppelin 0.5.6.
