Re: How to setup Zeppelin in AWS EC2

[Park Hoon]

Hi, Thanks for your opinion.

- Not every user uses spark and
- Some users might want to connect standalone Zeppelin with their existing
JDBC, elasticsearch, and so on.

That article might be too basic for you or advanced users. But I believe
our community has beginners and they can grow community more.

You might directly comment on the article about your points.

You can do easily `pip install py4j` with your python bin which related to
the python interpreter in Zeppelin.

Re: Unable to use angular backend or front end API to print variables

[Park Hoon]

Hi, regarding the difference

- (backend)
https://zeppelin.apache.org/docs/latest/displaysystem/back-end-angular.html
- (front)
https://zeppelin.apache.org/docs/latest/displaysystem/front-end-angular.html

In short,

- backend angular API works with other interpreters like spark, and so on.
So you can use angular API `z.angular*` with the existing interpreters (if
it's supported)
- on the other hand, frontend angular API provides `%angular`

Hi,

Zeppelin 0.7.1 was built using JDK 8, so it requires JDK8+

Could you test it with Zeppelin 0.7.2 and JDK7? It will work.

[DISCUSS] Release 0.8.0

[Park Hoon]

Hi, @user and @dev.

Recently, The last major release was about 5 months ago and many new
features bug fixes have been implemented / applied for few months.

Even though all features discussed in the thread before (“Roadmap for
0.8.0”[1]), some are available now.

So I think we can release 0.8.0 as the latest one while keeping 0.7.2 as
the most stable one as @moon suggested in the “Roadmap for 0.8.0” mailing
thread.

Shall we proceed to 0.8.0?

Here is the umbrella issue for the release 0.8.0. If you have issues to be
shared, Please add them to the ticket.

Official Docker Image for Apache Zeppelin 0.7.2

[Park Hoon]

Hi, users.

A few months ago the community started to create official docker image for
Zeppelin. As of 0.7.2, release process includes building docker image.
Thus, every release can ship its own docker image.

You can test the docker image for 0.7.2 with this command.

*docker run -p 8080:8080 --rm --name zeppelin apache/zeppelin:0.7.2*

or you can set docker volume options to persist notebooks and logs like

*docker run -p 8080:8080 --rm -v $PWD/logs:/logs -v $PWD/notebook:/notebook
-e ZEPPELIN_LOG_DIR='/logs' -e ZEPPELIN_NOTEBOOK_DIR='/notebook' --name
zeppelin apache/zeppelin:0.7.2*

And here are few links which might be helpful

- https://hub.docker.com/r/apache/zeppelin/
- https://github.com/apache/zeppelin/blob/master/docs/install/docker.md

Since this is an initial version, it might include some bugs or be not easy
to configure some options.

Hope that we can improve the docker file and deliver flexible images to the
community for various environments and use cases.

Thanks.

[DISCUSSION] Extending TableData API

[Park Hoon]

Hi All,

Recently, ZEPPELIN-753 
(Tabledata abstraction) and ZEPPELIN-2020
 (Remote method
invocation for resources) were resolved.
Based on this work, we can improve Zeppelin with the following enhancements:

* register the table result as a shared resource
* list all available (registered) tables
* preview tables including its meta information (e.g columns, types, ..)
* download registered tables as CSV, and other formats.
* pivoting/filtering in backend to transforming larger data
* cross join tables in different interpreters (e.g Spark interpreter uses a
table result generated from JDBC interpreter)

You can find the full proposal in Extending Table Data API

which
is contributed by @1ambda, @khalidhuseynov, @Leemoonsoo.

Any question, feedback or discussion will be welcomed.


Thanks.

Re: Question on a smoother transition of output graphs

[Park Hoon]

Hi, we can think few options. (of course and more)

1. Keep the previous result and set lower transparent for it while running
the paragraph.
2. Clean the previous output and keep the height at least.

and +1 for improving that part.


Thanks.

Re: Updating the official homepage

[Park Hoon]

Hi, All! Thanks for your opinion.

I think we can search in stackoverflow as well using tags.

- `apache-zeppelin`: 555 questions
- `apache-zeppelin` + `spark`: 264
- `apache-zeppelin` + `python`: 28
- `apache-zeppelin` + `hive`: 20
- `apache-zeppelin` + `cassandra`: 11
- `apache-zeppelin` + `jdbc`: 6
- `apache-zeppelin` + `sql`: 3
- `apache-zeppelin` + `elasticsearch`: 3

There are not tagged questions and SO might not reflect all usage.


Thanks. :)

Re: No 'Access-Control-Allow-Origin' header

[Park Hoon]

Hi afancy,


Webservers (e.g nginx, apache, spring and so on) basically do not allow
AJAX requests from other origin (host + ip).

(See https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS)

If you want your webserver to respond requests from other origin, you
should set proper options in the webserver.

You can refer this site: http://enable-cors.org/index.html


Thanks :)
