[GitHub] zeppelin issue #2237: ZEPPELIN-2377. Hive Support can not be enabled in spar...

[zjffdu]

Github user zjffdu commented on the issue:

https://github.com/apache/zeppelin/pull/2237
  
I don't prefer to call private method `hiveClassesArePresent` which is not 
guaranteed to be stable. The cause of hive support broken in spark master is 
due to we copied the implementation of `hiveClassesArePresent` of spark 2.0 in 
zeppelin, but `hiveClassesArePresent` is changed in spark master. So instead of 
checking difference classes for different versions, here I propose to checking 
class `InsertIntoHiveTable` which is public.

[GitHub] zeppelin issue #2241: ZEPPELIN-2390. Improve returnType for z.checkbox

[zjffdu]

Github user zjffdu commented on the issue:

https://github.com/apache/zeppelin/pull/2241
  
Before this PR It was not default to first item in checkbox, it is default 
to all items. The reason I change it to nothing is to make it consistent with 
scala implementation. 

Right, this would break the existing API, but I think it is worthwhile. I 
have several following PRs to improve `ZeppelinContext` and hope to stabilize 
it. IMO `ZeppelinContext` would play an important role for extending the rich 
functionality of zeppelin.

For

I mean either call hiveClassesArePresent (it's private yes) or do what it 
does?

[felixcheung]

Github user felixcheung commented on the issue:

https://github.com/apache/zeppelin/pull/2241
  
A bit concerned with breaking API changes like this but I guess we have 
never defined the support or versioning plan on the API?

Aren't we breaking the selected default item for checkbox by initializing
defaultChecked to empty?

It was default to first item in checkbox
Now is default to nothing

Add User Api

[omar abbas]

Hello,

I was wondering if you guys were working on a easier way to add users perhaps 
something that woulf let you add users to the shiro.ini page with out having to 
open the file because we do containerize our zeppelin image which we love by 
the way. Execing in to the container everytime though to add a new zeppelin 
user which we have alot of is a pain and not always the best. Do you think 
there will be some other way perhaps the same way we can make a credential rest 
request a user add rest request?

Thanks

[jira] [Created] (ZEPPELIN-2394) Auto-save on input is broken

[Ilia Fishbein (JIRA)]

 Summary: Auto-save on input is broken
 Key: ZEPPELIN-2394
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2394
 Project: Zeppelin
  Issue Type: Bug
  Components: Core, front-end
Affects Versions: 0.7.1, 0.7.0
Reporter: Ilia Fishbein


Commit 42be839 changed

```$scope.startSaveTimer();```

to

``` $scope.$broadcast('startSaveTimer');```

in zeppelin-web/src/app/notebook/paragraph/paragraph.controller.js

for seemingly no reason and did not include corresponding code that registers a 
"startSaveTimer" event.

As a result, paragraphs are not auto-saved based on end-user input.

In some cases, depending where authentication server is deployed and what

403 Forbidden response by cloudflare service with error-code 1010.

[ZEPPELIN-2217][WIP] AdvancedTransformation for Visualization

### What is this PR for?

`AdvancedTransformation` has more detailed options while providing existing 
features of `PivotTransformation` and `ColumnselectorTransformation` which 
Zeppelin already has 


![av_in_30sec](https://cloud.githubusercontent.com/assets/4968473/24037330/c9478e86-0b40-11e7-9886-1ffb85042a7a.gif)

Here are some features which advanced-transformation can provide.

1. **(screenshot)** multiple sub charts
2. **(screenshot)** parameter widgets: `input`, `checkbox`, `option`, 
`textarea`
3. **(screenshot)** expand/fold axis and parameter panels
4. **(screenshot)** clear axis and parameter panels
5. **(screenshot)** remove duplicated columns in an axis
6. **(screenshot)** limit column count in an axis
7. configurable char axes: `valueType`, `axisType`, `description`, ...
8. configurable chart parameters
9. lazy transformation
10. parsing parameters automatically based on their type: `int`, `float`, 
`string`, `JSON`
11. multiple transformation methods
12. re-initialize whole configuration based on spec hash.
13. **(screenshot)** shared axis

 API Details: Spec

`AdvancedTransformation` requires `spec` which includes axis and parameter 
details for charts.

- Let's create 2 sub-charts called `simple-line` and `step-line`.
- Each sub chart can have different `axis` and `parameter` depending on 
their requirements.

```js
  constructor(targetEl, config) {
super(targetEl, config)

const spec = {
  charts: {
'simple-line': {
  sharedAxis: true, /** set if you want to share axes between sub 
charts, default is `false` */
  axis: {
'xAxis': { dimension: 'multiple', axisType: 'key', },
'yAxis': { dimension: 'multiple', axisType: 'aggregator'},
'category': { dimension: 'multiple', axisType: 'group', },
  },
  parameter: {
'xAxisUnit': { valueType: 'string', defaultValue: '', 
description: 'unit of xAxis', },
'yAxisUnit': { valueType: 'string', defaultValue: '', 
description: 'unit of yAxis', },
'dashLength': { valueType: 'int', defaultValue: 0, description: 
'the length of dash', },
  },
},

'step-line': {
  axis: {
'xAxis': { dimension: 'single', axisType: 'unique', },
'yAxis': { dimension: 'multiple', axisType: 'value', },
  },
  parameter: {
'xAxisUnit': { valueType: 'string', defaultValue: '', 
description: 'unit of xAxis', },
'yAxisUnit': { valueType: 'string', defaultValue: '', 
description: 'unit of yAxis', },
'noStepRisers': { valueType: 'boolean', defaultValue: false, 
description: 'no risers in step line', widget: 'checkbox', },
},

  },
}

this.transformation = new AdvancedTransformation(config, spec)
  }
```

  API Details: Axis Spec

| Field Name | Available Values (type) | Description |
| --- | --- | --- |
|`dimension` | `single` | Axis can contains only 1 column |
|`dimension` | `multiple` | Axis can contains multiple columns |
|`axisType` | `key` | Column(s) in this axis will be used as `key` like in 
`PivotTransformation`. These columns will be served in `column.key` |
|`axisType` | `aggregator` | Column(s) in this axis will be used as `value` 
like in `PivotTransformation`. These columns will be served in 
`column.aggregator` |
|`axisType` | `group` | Column(s) in this axis will be used as `group` like 
in `PivotTransformation`. These columns will be served in `column.group` |
|`axisType` | (string) | Any string value can be used here. These columns 
will be served in `column.custom` |
|`maxAxisCount` | (int) | The maximum column count that this axis can 
contains. (unlimited if `undefined`) |
|`valueType` | (string) | Describe the value type just for annotation |

Here is an example.

```js
  axis: {
'xAxis': { dimension: 'multiple', axisType: 'key',  },
'yAxis': { dimension: 'multiple', axisType: 'aggregator'},
'category': { dimension: 'multiple', axisType: 'group', 
maxAxisCount: 2, valueType: 'string', },
  },
```

  API Details: Parameter Spec


| Field Name | Available Values (type) | Description |
| --- | --- | --- |
|`valueType` | `string` | Parameter which has string value |
|`valueType` | `int` | Parameter which has int value |
|`valueType` | `float` | Parameter which has float value |
|`valueType` | `boolean` | 

Re: Custom Interpreter group is not displayed on the GUI

[Minudika Malshan]

Hi,

Thanks for the quick reply.
I followed that documentation. But after installing the interpreter using
that given command, still my interpreter group is not listing when I try to
create a interpreter from UI.

In the interpreter-settings.json I have given "wso2" as my interpreter
group[1].
Is there anymore configuration to be done to bind it with the zeppelin?

I am writing a custom interpreter for apache zeppelin. I added the
interpreter class to the zeppelin-site.xml and also updated the
interpreter-setting.json of my interpreter's module.
But when build the project and start the zeppelin server, the interpreter
group I given for my interpreter is not shown in the drop down.
Could you please let me know how to resolve this?

Please find my code here. [1]

Also I have committed my current updated zeppelin-site.xml.

Thank you!

ZEPPELIN-2390. Improve returnType for z.checkbox

### What is this PR for?
Currently it is not convenient to access the individual item of the return 
value of z.checkbox, I would propose to return `Seq` for `SparkInterpreter` and 
`list` for `PySparkInterpreter`.  This might cause some incompatibility, but I 
think it is acceptable considering the benefits.  Besides that, before this PR, 
all the items of checkbox would be checked by default in `PySparkInterpreter` 
which is inconsistent with `SparkInterpreter`, so I change it to nothing is 
selected by default in this PR. 

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

### Todos
* [ ] - Task

### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-2390

### How should this be tested?
Unit test is added

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

 Summary: Cannot initialize SparkContext on CDH5.7
 Key: ZEPPELIN-2391
 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2391
 Project: Zeppelin
  Issue Type: Bug
  Components: Interpreters
Affects Versions: 0.7.1
 Environment: OS: CentOS 6.8
Kernel: 2.6.32-642.el6.x86_64
CDH: CDH-5.10.0 (Hadoop version: 2.6.0-cdh5.10.0)
Reporter: Tony Liu


I built Zeppelin 0.7.1 from source with the following command:
mvn clean package -Pspark-1.6 -Dspark.version=1.6.0 -Phadoop-2.6 
-Dhadoop.version=2.6.0-cdh5.10.0 -Pvendor-repo -DskipTests -Pbuild-distr

But when I create a new note with Spark interpreter and run sc.version, it 
gives this error:
java.lang.NoSuchMethodError:

GitHub user soralee reopened a pull request:

https://github.com/apache/zeppelin/pull/2133

[ZEPPELIN-1357,1892,1370][Umbrella] Text overlap in the MultiBarChart

### What is this PR for?
If using the `multiChartBar`, it often occurs overlap in text. So, this PR 
is for preventing to overlap in text. 

>~~The below is the case what I updated.~~
~~1. The xLabel generally show all of the text without rotation (less than 
30).~~
~~2. If the xLabel size is over than 30 and less than 80, the xLabel text 
are rotated as 90 degree and displayed.~~
~~3. If the xLabel size is over than 80, the xLabel text are disappeared, 
but the tooltip is displayed.~~
>~~I have made improvements based on my thinking, so I would appreciate to 
give me your feedback.~~
~~And if merged this PR, I'll update the feature so that user can use `min` 
and `max` variables by user on web.~~

**[Update]**
To prevent overlap in xLabel text, in one way which is talked the below 
mentions, user who is using zeppelin could select to visualization type of 
xLabel such as `rotate 45 degree` or `hide`.

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

### What is the Jira issue?
* [ZEPPELIN-1357; UI - label wrapping not done properly in 
charts](https://issues.apache.org/jira/browse/ZEPPELIN-1357)
* [ZEPPELIN-1892; Display label vertically or horizontally 
smartly](https://issues.apache.org/jira/browse/ZEPPELIN-1892)
* [ZEPPELIN-1370; Label overlaps - in default visualization example 
barchart](https://issues.apache.org/jira/browse/ZEPPELIN-1370)

### How should this be tested?
1. Run the paragraph for bank data in  the `Basic Features (Spark)` 
notebook.
2. Execute the following query.
``` 
%sql
select * from bank
```
3. Use the pivot in the `Setting` toggle in the `MultiBarChart` such as the 
screenshots.

ZEPPELIN-2386. Add parameter for check running current paragraph in 
ZeppelinContext

### What is this PR for?
I can reproduce it via the test code in ZeppelinIT.testAngularDisplay. 
First run the 4 paragraphs to initiate the state. Then when I click paragraph 0 
the first time, paragraph 2 will run correctly. But if I click paragraph 0 
again, interpreter would raise the following exception. The cause is that 
ZeppelinContext's interpreterContext now point to paragraph 2, because 
paragraph 2 is the last paragraph that runs in this interpreter. So I propose 
to add parameter to
