tLogRow Not working: no column names if more than 50 rows

cleanDataBaby — Fri, 15 Nov 2024 22:35:44 GMT

Hello,

I'm new to talend but this issue looks like a bug to me.

I have a csv file with 90000+ rows when I bring that file in I define the schema and everything, then when I log the row I can see only a bunch of the records but I dont get any column names. Which defeats the purpose logging the row, I want to see the data as I am working with it.

to make sure my schema and csv settings are correct, I changed the row limit to 50 and it works, even at 100 rows it doesn't show.

Is this a bug, or am I doing something wrong. my other file has like 500 rows and that one shows column names. ( the main difference between the two is the number of columns can that be causing this issue?)

Please let me know how to fix this issue, I have included screenshots below. sorry about the black highlights cant share the data.

Thanks in advance

Hello,

Could you please clarify in which Talend version/edition you are?

This looks like a Studio console display issue when the data to print/display is too large. Please try to replace tLogRow with any tFileOutputXXX component to confirm.

Best regards

Sabrina

Thank you for your response, yes with tfileoutput it works. Is this is known bug with tlogrow?

Hello,

Sorry for getting back to you late.

I tried generate 200 rows from tRowGenerator component and tLogrow displays good with line limit 100. Feel free to let me know if I miss something.

Best regards

@Xiaodi Shi Hi Sabrina,

No problem, i'm sure you are very busy.

I think the issue exists only when you use CSV files, can you try using a csv file and use tfileinputdelimited and see if the problem persists.

perhaps I need to configure something in the application settings.

please let me know. It can also be the version of java I use. What version are you using?

Thanks again

Hello,

I installed JDK 11 when using Talend Open Studio for Data Integration 8.0.1.

I will try using a csv file and use tfileinputdelimited and see if the problem persists and then come back to you as soon as possible.

Best regards

Sabrina
