Talend Data Prep on MacOS High Sierra

[Anonymous]

I downloaded the free version of Talend Data Prep as a MacOS DMG file from this website. I then dragged the application into my applications folder. When I start Talend Data Prep, the website opens in my default browser. 

There I can see the available datasets and the preparations. But when I click onto one of the datasets, or on one of the preparations or when I want to create a new preparation, I get various errors as red ballon tips on the upper right. Unfortunately the errors don't indicate what went wrong exactly. 

In the current state I can not use Talend Data Prep. 

Any idea how to solve that?

Hi Matthias,

Can you first disable App Nap for Data Prep as indicated here https://help.talend.com/reader/mime3pPIS~faiBvVb~FT7w/b006EaGseLmCHC2Tx__deg and let me know if you still face the same issues?

Thank you,

Hi.

Now I can select an existing dataset and a new data preparation view opens. But opening an existing data preparation does not work. If I create a new data prep I still get an error. Nevertheless, the data prep will be in the list afterwards. But can't open it anyway. See screenshot.

Can you share the log file app.log, which is in Library/Application Support/Talend/dataprep/logs/?

Assuming that the source dataset does not contain sensitive data, could you share it as well? That would allow us to reproduce.

Thank you,

Gwendal

I have the same problem. I have tried and tried, it runs a little faster if I invoke the app from the terminal, but always the same problem. 

Here is the console output:

Hi Matthias,

I'm able to reproduce your issue, but only if I re-enable the AppNap functionality. Could you please tell me what you get if you enter the following command in you terminal ?

defaults read org.talend.dataprep NSAppSleepDisabled

Thank you,

Nicolas

Output on the terminal is: 1

Ok so AppNap is well disabled. I don't know why you're facing this timeout, but we can try to increase his value to  work around your problem.

Could you kill your Data Preparation daemon then try to enter the following commands in your terminal, please ?

cd /Applications/Talend\ Data\ Preparation\ Free\ Desktop.app/Contents/Java

unzip Talend-DataPreparation-Free-Desktop-macos-2.5.1.jar application.properties

echo "hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=300000" >> application.properties

jar -uf Talend-DataPreparation-Free-Desktop-macos-2.5.1.jar application.properties

Then you can restart Data Preparation.

Thank you,

Nicolas
