Re: Paragraph text editor is very slow when number of notes is large (> 1000)

[Corneau Damien]

Might be hard to reproduce if we need to have 1000 notes.
And its also difficult to figure it out without more informations.

I don't think there is a real short-term workaround, If the issue is from
the notebook list, then using bind-once on that list could maybe have an
impact.
Otherwise things will get better as the code get cleaned up.

Re: command execution time measure

[Corneau Damien]

Hi Herman,

This issue was fixed some time ago. (
https://issues.apache.org/jira/browse/ZEPPELIN-1161)
It should be fixed in 0.6.1
It is fixed in Master right now for sure.

Re: Adding main and access titles to Zeppelin's chart

[Corneau Damien]

Hi,
For some charts, the legend of the Yaxis has the name of the data.
However there is currently no option to add a Title, or Axis Title.

You can probably create a Jira Issue for that

Re: Unable to change the height of paragraphs after upgrade 0.5.6 to 0.6.1

[Corneau Damien]

Hi,

The way it worked may have changed between 0.5.6 and 0.6.1 in the way that
only the result size can be changed instead of the whole paragraph.
In the case of the Table and Graph, you can resize up or down as much as
you want (there is still a minimum height though).
For basic Text type, you can resize down to the minimum height, and up to
the maximum height of the text.

I will check in the 0.6.1 release in case, but at least it is working well
in the master branch

Re: table render string to long

[Corneau Damien]

Hi dengjh,

It seems to be an effect of a recent commit that try to detect Numbers.(
https://github.com/apache/zeppelin/pull/1371)
I think this PR https://github.com/apache/zeppelin/pull/1363, would be able
to fix this issue as it would allow users to specify the type by themselves.

However keep in mind that this behavior is only applied in the Table, and
the value should be as a string in charts

Re: How to use web sockets with Zeppellin

[Corneau Damien]

There might actually be another way to do that using python or scala code.

I don't have experience in those, but I guess the overall idea behind it
would be to have this type of code in a paragraph that you run:


// Include python websocket library

// pythonWebsocketOpenConnection(myServerWithData)

// pythonWebsocketEventListener(event) {
//   transform data to be in the format "product\tprice\nbanana\t12\
napple\t8"
//   print("%table " + event.data )
//}

This example is for the result of a single paragraph (the one with the
code),
However if you receive result for multiple graphs in that hook, you could
probably prepare other paragraphs with something like:

//  print("%table " + graphData1 )

and change the original hook in previous example to do
// pythonWebsocketEventListener(event) {
//   graphData1 = event.data.graph1 (transformed in the format
"product\tprice\nbanana\t12\napple\t8")
//   z.runParagraph(paragrpahID) (The one with the graphData1, the ID is in
the paragraph dropdown settings)
//   etc...
//}

Re: How to use web sockets with Zeppellin

[Corneau Damien]

To reply to 1)

The type of  charts and its options are set in the UI, and saved as
settings in the note.
So the queries do not have any effect on it.

The front-end receive data as a result of a query.

for example:

You can type

```
%sql
select * from bank
```

And the front-end will receive a table like result in the form of:

"product\tprice\nbanana\t12\napple\t8"

It will first show it as a Table, but the UI allows you to change the
visualization type.


To reply to 2)

I don't have any knowledge of a websocket interpreter.

However like I explained before in the Zeppelin workflow,
Zeppelin Server send a Query through an interpreter to whatever type of
backend, and gets a result back.
It then send back that result to the UI.

A Spark interpreter is used to query Spark,
A JDBC interpreter is used to query SQL server
and so on...
(We even have a shell interpreter)

If you are using something custom outside of the existing data
processing/data store technology we have,
and you want to make Zeppelin communicate with it to render data, you will
need to create a custom interpreter.

Re: How to use web sockets with Zeppellin

[Corneau Damien]

This change wouldn't solve your issue, it is the address where the
front-end send his API requests and listen to WS (zeppelin server)
I guess your requirements are different.

The way Zeppelin works is usually pretty simple:

1) You type your code in the front-end
2) That code is sent to Zeppelin server to be run
3) The server send it to the right processing engine
4) Processing engine send back the result
5) Zeppelin Server send a websocket event
6) Front-end show whatever he receives

You might be able to find a few Notebook examples on how some people used
Spark Streaming here:

Re: donut chart

[Corneau Damien]

Hard to know, I have no problem importing it in Master or branch-0.6
If there is an issue, it should show in the browser's console.

All of the default charts of Zeppelin rely on nvd3.

That custom one uses the existing library, and do not import any other so
there shouldn't be any issue

Re: donut chart

[Corneau Damien]

I just tried it on Master and branch-0.6 and have no problem rendering this
Notebook.
There is supposed to be one chart in between "Inline front-end rendering
visualization" and "Inline back-end rendering visualization"
Any error in the console?

No, it wasn't merged.
Is there some special use cases to use donut instead of pie chart?

Re: Filter query results by current user

[Corneau Damien]

There was a thread opened not that long ago in the mailing list with a
similar use case.

In short, there is currently no way to have changes made without those
changes being saved.

Re: [ANNOUNCE] Apache Zeppelin 0.6.0 released

[Corneau Damien]

FYI, the Helium logs in the console should be on master, but not on 0.6.0
branch.
Those 500 errors should not have any effect when running.

This is happening in the grunt.js

But why would you want to remove it? This is a basic production build rule.

Re: Cannot copy data in tables in Zeppelin 0.6.0

[Corneau Damien]

No problem, it can be hard to find the exact issue in JIRA, and the PR is
quite recent.
Hopefully you will be able to get a version of Zeppelin with that change
soon.
There is also a paragraph data download feature in the master right now, in
case it would help
