But lots of company run production on Docker though, just FYI. Either

[agoodm]

GitHub user agoodm opened a pull request:

https://github.com/apache/zeppelin/pull/1343

ZEPPELIN-1328 - z.show in python interpreter does not display PNG images in 
python 3

### What is this PR for?
Support for plotting PNG images via matplotlib inline for the python 
interpreter was recently added (#1329). However, these changes did not work for 
python3 since it handles strings differently. This PR aims to make the inline 
plotting compatible with both python 2 and 3. 


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

### What is the Jira issue?
* [ZEPPELIN-1328](https://issues.apache.org/jira/browse/ZEPPELIN-1328)

### How should this be tested?
In a python interpreteter cell, make sure the following produce an image:
```python
%python
import matplotlib.pyplot as plt
import numpy as np

x = np.arange(5)
plt.plot(x)
z.show(plt, fmt='png') # Repeat for fmt='svg'
```
This should be tested for both python2 and 3 interpreters (via the 
interpreter settings page). 

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

z.show(plt)
{code}

This style of inline notebook plotting has many limitations compared to that 
found in Jupyter, which of course has the advantage of being built natively in 
python as well as connections with the core matplotlib development team. This 
means for example in a Jupyter notebook, you can easily create an inline plot 
using

{code}
% matplotlib inline
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(5)
y = 2*x
plt.plot(x, y)
plt.show()
{code}

You could even omit the call to {{plt.show()}} if the version of matplotlib you 
are using is 1.5 or later, and enable some interactive features similar to 
those in found in D3.js (like panning and zooming) if you instead use 
{{%matplotlib notebook}} at the top of the notebook cell. 

In order to accomplish this in zeppelin, we will first need to make our own 
custom matplotlib backend (I'll explain this in more detail in a separate JIRA 
issue). To summarize, these are the improvements in our matplotlib integration 
that should be made:

- Create a custom matplotlib backend for plotting inline images
- Support interactive plotting

On top of this, all of these changes should be ported to the pyspark 
interpreter as well since there are probably many users who would like to have 
matplotlib plotting in their spark related workflows.

 Summary: Create a custom matplotlib backend that natively supports 
inline plotting in a python interpreter cell
 Key: ZEPPELIN-1345
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1345
 Project: Zeppelin
  Issue Type: New Feature
  Components: python-interpreter
Affects Versions: 0.7.0
Reporter: Alex Goodman
Assignee: Alex Goodman
 Fix For: 0.7.0


This is a sub-task for ZEPPELIN-1344. The deliverable will be a custom 
matplotlib backend which natively supports inline plotting in zeppelin notebook 
cells (for the python and eventually pyspark interpreters). More information 
regarding matplotlib backends can be found here:

http://matplotlib.org/faq/usage_faq.html#what-is-a-backend

The focus of this issue will be getting support for plotting just static images 
similar to those generated in a Jupyter notebook cell when {{%matplotlib 
inline}} is used. Getting support for more interactive plotting will also 
require a custom backend that will be based off of this one.

improving matplotlib integration in zeppelin

[Goodman, Alexander (398K)]

Hi all,

As per previous discussion I had with Alex Bezzubov on the users mailing
list, I have created two new JIRA issues ([1] and [2]) explaining in more
detail what I think we should ultimately strive for in our ongoing work to
improve matplotlib integration in zeppelin. For now I think I will be able
to handle the bulk of the work for the static images backend issue
[ZEPPELIN-1345] on my own, but more collaboration will be needed to get
interactive plotting to work.  Please feel free to discuss any thoughts or
suggestions you may have here.

[1] - https://issues.apache.org/jira/browse/ZEPPELIN-1344

Issues in Zeppelin 0.6.0

[Nagasravanthi, Valluri]

Hi,

I am using Zeppelin 0.6.0. Please find below the issues along with their 
detailed explanation.

Zeppelin 0.6.0 Issues:

a.   not able to execute DDL statements like Create/Drop tables using 
temptables derived from the hive table

* Error Log: "java.lang.RuntimeException: [1.1] failure: ``with'' 
expected but identifier drop found : When using sql interpreter to drop"



b.  not able to use the HiveContext to read the Hive table

* Error Log: "error: object HiveContext in package hive cannot be 
accessed in package org.apache.spark.sql.hive"

Detailed Explanation:
I upgraded to 0.6.0 from Zeppelin 0.5.6 last week. I am facing some issues 
while using notebooks on 0.6.0. I am using Ambari 2.4.2 as my Cluster Manager 
and Spark version is 1.6.

The workflow of notebook is as follows:

1.   Create a spark scala dataframe by reading a hive table in parquet/text 
format using sqlContext (sqlContext.read.parquet("/tablelocation/tablename")

2.   Import sqlcontext_implicits

3.   Register the dataframe as a temp table

4.   Write queries using %sql interpreter or sqlContext.sql

The issue which I am facing right now is that Even though I am able to execute 
"SELECT"  query on the temptables but I am not able to execute DDL statements 
like Create/Drop tables using temptables derived from the hive table.
Following is my code:
1st case:  sqlContext.sql("drop if exists tablename")
2nd case: %sql
  drop if exists tablename

I am getting the same error for both the cases: java.lang.RuntimeException: 
[1.1] failure: ``with'' expected but identifier drop found : When using sql 
interpreter to drop

It is to be noted that, the same code used to work in Zeppelin 0.5.6.

After researching a bit, I came across that I need to use HiveContext to query 
hive table.

The second issue which I am facing is I was able to import HiveContext using 
"import org.apache.spark.sql.hive.HiveContext" but I was not able to use the 
HiveContext to read the Hive table.

This is the code which I wrote :
(HiveContext.read.parquet("/tablelocation/tablename")

I got the following error:
error: object HiveContext in package hive cannot be accessed in package 
org.apache.spark.sql.hive

I am not able to deep dive into this error as there is not much support online.

Could anyone please suggest any fix for the errors ?

Thanks and Regards,

Re: Issues in Zeppelin 0.6.0

[Jeff Zhang]

Hi

Since you have many issues, let's focus one issue first.

>>> *not able to use the HiveContext to read the Hive table*


Can you paste your code of how you use HiveContext ? Do you create it by
yourself ? It should be created by zeppelin, so you don't need to create it.
What's  in interpreter log ?

[GitHub] zeppelin issue #1339: [WIP][ZEPPELIN-1332] Remove spark-dependencies & sugge...

[bzz]

Github user bzz commented on the issue:

https://github.com/apache/zeppelin/pull/1339
  
@AhyoungRyu great initiative, but while making this changes, you have to 
think also about CI use case of zeppelin build as well.

I.e so far `/.spark-dist/` is under cache on TravisCI which is S3 bucket 
that gets synced automatically with the content of this folder while running a 
build. It you un-tar the whole archive there - it will take forever to sync \w 
S3 and will defeat the purpose of cache on CI side, making build times longer.

If you ask me - I would say that before doing such big changes as 
refactoring of the build structure we all need very clear understanding and 
explanation of `what is the benefit` and what problem does this change solves. 

So far I have not understood the answer to the questions above from PR 
description (may be my fault). But, in case of voting for such change, will 
make me at least `-0` for if, if not `-1` due to potential bugs that such 
changes will bring.

If that is reduction of convenience binary size - then we need to know how 
much does the size changes with the proposed changes to understand if that is 
worth. If that impacts CI build times - we also need to know how much.

Also regarding user experience - while running `zeppelin-demon.sh` user 
does not usually expect it to be network-dependant and download 100Mb archives 
- is there at least a user notification\progress indicator? Otherwise there 
going to be bug reports like "Zeppelin is not starting" as soon as such change 
is introduced. 
And how about Windows users of Zeppelin? How about EMR\Dataproc\Juju\BigTop 
users, will the proposed change affect them?

Please take it with the grain of salt, and of course I will be happy to 
help addressing each item addressed one by one.

[bustios]

Github user bustios commented on the issue:

https://github.com/apache/zeppelin/pull/1343
  
@agoodm your solution looks good, but the `import io` is going to generate 
an error in the `show_dataframe` method for Python 2. Running the tests can 
help you to catch this error. It would be better to use:

```python
from io import BytesIO
```
before (and not to delete):
```python
try:
import StringIO as io
except ImportError:
import io as io
```
another option could be:
```python
from io import BytesIO
try:
from StringIO import StringIO
except ImportError:
from io import StringIO
```
and replage `io.StringIO` by `StringIO`.

Personally, I prefer the second option because it has the advantage of 
avoiding the `io` package to be hidden by `import StringIO as io` for future 
use.

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

[bzz]

Github user bzz commented on the issue:

https://github.com/apache/zeppelin/pull/1231
  
> If you are expecting to code the entire DHT from scratch, it's too tough 
for me

That is not an expectation here of course. 

Let's think about alternatives - another way is to distribute note.jspn 
though regular torrents, right? So we can assume that there is going to be a 
tracker one day, that lists all notebook that are shared and each Zeppelin 
instance will be just seeding it's own fraction of notebooks.

Then each revision of the note need to be stored as a separate file, as it 
will create a new torrent file\magnet link, right?

Do you think this will work?

 1. listing existing notes that shared through Bittorrent

  This will include listing local copies from filesystem i.e under 
`/notebook/bittorent` or `/notebook-bittorent` not to interfere \w existing 
VFSNotebookRepo impl.

 2. checkpointing AKA creating revisions
  Each revision will result in a new file i.e `note-revisionId.json` + a 
new .torrent/magnet link to share it

 3. listing revisions for each note
  This should be simple, given the assumptions from above. And each 
revision can be shared independently

 4. importing new note by magnet link (should work similar to current 
"import by URL")

[Leemoonsoo]

Github user Leemoonsoo commented on the issue:

https://github.com/apache/zeppelin/pull/1333
  
@zjffdu Tested and It looks good to me.

There is an unittest for set environment variable for remote interpreter at 
[RemoteInterpreterTest.java](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/test/java/org/apache/zeppelin/interpreter/remote/RemoteInterpreterTest.java#L721).
 However, the unit test is not testing the case this fix addresses.

It's not going to be a blocker but I think it'll be really beneficial to 
have a unittest that covers this fix, somewhere in 
[InterpreterFactoryTest.java](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/test/java/org/apache/zeppelin/interpreter/remote/RemoteInterpreterTest.java).
 @zjffdu Is it going to be difficult to add the test?  Let me know if you need 
any help!

In my opinion, since the editor itself is not available, it shouldn't focus 
that paragraph which is also behaviour after this PR

Re: improving matplotlib integration in zeppelin

[moon soo Lee]

Hi,

It's great to see improving matplotlib integration. Thanks a lot.

In my understanding, in interactive mode, the graph supposed to be updated
even if some matplotlib methods are called in the other paragraph(cell).
That means the result of a paragraph need to be updated by running another
paragraph.

Currently, i think there're two different facilities in Zeppelin to do that.

One possible way is using InterpreterContextRunner [1]. InterpreterContext
provides InterpreterContextRunner[2] and it gives ability to run other
paragraphs in the same note. However this approach does have some
limitations. Like if paragraph (cell) is in the other notebook, interactive
update of graph will not work anymore. And because it's not only update the
result of the other paragraph, but also run the other paragraph, it'll be
difficult to make interactive mode work correctly depends on user code in
each paragraphs.

Second possible approach is using AngularDisplay system.
Which allows interpreter send/receive some data and event from/to front-end
side.
So without rerun another paragraph, it's possible to update result of a
paragraph from another.
Any interpreter can get AngularObjectRegistry[3] from InterpreterContext
[4], and AngularObjectRegistry allows create object / add event hook to
communicate with front-end. I think this is more feasible approach.

Thanks,
moon
