@r-kamath build fails with

Failed tests: SparkParagraphIT.testSqlSpark:169 Paragraph from SparkParagraphIT of testSqlSpark result: Expected: "age job marital education balance\n30 unemployed married primary 1,787"
but: was "age\njob\nmarital\neducation\nbalance\n30 unemployed married primary 1787\nage\njob\nmarital\neducation\nbalance"

Looks like this require selenium test update.

astroshim · 2016-04-26T14:35:53Z

I passed the build with no problems and functionality is working very well.
but @r-kamath you should make the green CI.
Thanks.

felixcheung · 2016-04-26T18:49:07Z

How does this work with some of the pending data table changes?
like #6, #714, #725, #761

r-kamath · 2016-04-27T10:16:21Z

Won't affect #714 and #725

#6 and #761 are using jQuery Datatables
This PR is a proposal to use Handsontable instead of datatables. Handsontable is more like a spreadsheet and has good performance with many builtin features and plugin support.

I've done a basic performance test with 20000x80 rows and columns data and few paragraphs with a subset.

felixcheung · 2016-04-27T20:52:29Z

We would need export to file feature which seems like is not supported in the free Handsontable version?

r-kamath · 2016-04-28T04:45:14Z

Right, it is supported only in pro ver. Handsontable's Export feature is in front-end. IMHO export should be a backend feature and will be a good addition to our Notebook REST api.

+ <script src="bower_components/moment/moment.js"></script>
+ <script src="bower_components/pikaday/pikaday.js"></script>
+ <script src="bower_components/handsontable/dist/handsontable.js"></script>


pickaday.js, moment.js, ZeroClipboard.js, pikaday.css are they required to use handsontable?

ZeroClipboard and pikaday.js are not required, need to see how to remove them from the build.
As of now moment.js is used only for number formatting (7bb508e)

I was wrong. All three deps are required. Use without pikaday #2841

Leemoonsoo · 2016-04-28T18:15:57Z

Is it possible to handle '%html' inside of table cell?

if i run

println(s"""%table key\tvalue
html\t%html <dev style='color:blue'>blue</div>
""")

r-kamath · 2016-04-28T18:22:04Z

@Leemoonsoo that's in the todo list. Can be done either in FE or in server. Thoughts?

r-kamath · 2016-04-29T09:47:04Z

@Leemoonsoo%html rendering is fixed in a96c94a

Leemoonsoo · 2016-04-30T03:31:57Z

%html rendering is working nicely! If pickaday.js, moment.js, ZeroClipboard.js are required to use handsontable, they also need to be in 'zeppelin-distribution/src/bin_license/LICENSE'

…into ZEPPELIN-830

r-kamath · 2016-05-02T07:19:07Z

@Leemoonsoo license doc updated and rebased 2e422ea4fbb22b

prabhjyotsingh · 2016-05-04T16:13:22Z

LGTM! nice improvement 👍

Leemoonsoo · 2016-05-04T18:07:38Z

@r-kamath Are there any more works left for unchecked todo item 'UI fixes', in the description of this PR?

r-kamath · 2016-05-04T18:14:38Z

@Leemoonsoo the only pending item is the sort header arrow style. Should we try something more stylish ?

Leemoonsoo · 2016-05-04T18:23:06Z

Arrow style looks fine. I think it's good to be merged!

r-kamath · 2016-05-04T18:26:08Z

@Leemoonsoo cool. I have checked the 'UI fixes'. thanks

Leemoonsoo · 2016-05-04T18:29:23Z

Last CI test failure is unrelated to the change. LGTM.

felixcheung · 2016-05-04T21:15:58Z

does this PR change the export to CSV capability?

corneadoug · 2016-05-05T00:35:57Z

@felixcheung No, There is still no export to CSV feature

r-kamath · 2016-05-05T07:12:07Z

@felixcheung this PR is only for improving table performance. CSV/TSV export is in #725 and #714

prabhjyotsingh · 2016-05-09T13:32:05Z

@r-kamath can you resolve branch conflict.

prabhjyotsingh · 2016-05-10T06:48:53Z

Thanks @r-kamath for contributing towards front-end performance.
Merging if no more discussion.

corneadoug · 2016-05-10T11:31:10Z

Anyway to not have:

zeroclipboard
pikaday
moment

included when installing Handsontable?

r-kamath · 2016-05-10T12:08:25Z

@corneadoug Use without pikaday #2841

corneadoug · 2016-05-10T12:15:09Z

@r-kamath https://github.com/handsontable/hot-builder
I understand that by default it seems to be needed, however I'm reticent to include 3 different dependencies that we are not using.

r-kamath · 2016-05-10T12:28:05Z

Not sure if we can avoid those dependencies by choosing hot-builder!
Though we are not using the copy/ paste, date picker and date formatting, it is still a feature in Handsontable.
IMO we shouldn't be worried about those three dependencies because it is not a part of our web bower.json

prabhjyotsingh · 2016-05-10T13:56:42Z

I would agree with @r-kamath, as long as those dependencies are not been written in bower.json we should be ok.
https://github.com/apache/incubator-zeppelin/pull/858/files#diff-6bcc7568e5b6af0b1499ab172fc66af4L33

corneadoug · 2016-05-10T14:56:03Z

I don't get why its not important to have unused additional dependencies in our build, as long as its not in bower.json, maybe somebody can explain more.

r-kamath · 2016-05-10T15:16:18Z

@corneadoug Again, this is an issue on handsontable please follow these links. Those entries in index.html should disappear when handsontable team fix the issue.
handsontable/handsontable#2841
handsontable/handsontable#2974

Also it is included in the Improvement-suggestions section.

More details here : https://github.com/handsontable/handsontable

@Leemoonsoo @prabhjyotsingh what say?

corneadoug · 2016-05-12T07:33:08Z

@r-kamath I don't want to make this PR wait forever.
If it was easy to do, I would prefer removing those dependencies. Mainly because everytime we want to add a dependency, we should ask ourselves if its really necessary, so adding 3 dependencies that are not being used is even worst.

Since Handsontable seems to be helpful in term of performances, it might still be worth it to have those unnecessary dependencies. However, after this PR, we should try to find a way to get rid of them somehow (by keeping an eye for a fix in handsontable, or making a PR there, or even trying their hotbuilder)

r-kamath · 2016-05-12T15:05:43Z

@corneadoug I'm following up on handsontable repo. Will find some time to explore for a potential PR.

corneadoug · 2016-05-12T15:07:23Z

ghost · 2016-05-20T01:26:24Z

Great Job. I have a silly question, how do you debug your code in zeppelin, I mean , what IDE do you use and how you make breakpoint or sth like that ...

corneadoug · 2016-05-20T01:36:01Z

@yantaiv Better ask that in the mailing list, you would get more answers
But overall:
You can use any IDE you want, there is informations about dev mode in the README

gauravkumar37 · 2016-06-03T05:32:08Z

Thanks for the wonderful commit.
However, I faced one issue. I am not able to select any data in the table using mouse for copying it. (checked on FF & chrome latest versions)
