Big Data / Positional File

_AnonymousUser — Sat, 16 Nov 2024 11:44:46 GMT

Hello Guys,
I would like to know if it is possible (with Talend Enterprise edition for Big Data) to create a MapReduce job in order to handle Positional Files(file delimited by lenghts)?
Thank you in advance

Hi,
Are you looking for "Metadata" section in Talend Enterprise edition for Big Data? So far, tFileInputPositional haven't supported for MapReduce yet.
It welcome to open a new feature jira issue of DI project on Talend Bug Tracker.
Best regards
Sabrina

Hi?
Would you mind pasting your file without explicit separators into forum? So far, TalendHelpCenter:tFileInputJSON belongs to the MapReduce component family.
You can open a jira issue of DI project for your requirement on Talend Bug Tracker.

Hi,
it is simple format as:
aaa1245bbe12df4
bbb5462adfd45df
Lenghts would be 3, 4, 2, 6.
Json could handle that?

Thank you

I just saw tStandardizeRow module.
Would it be possible to split my file by using RegEx ?
For exemple i want to say:
the 1st row is from 1 to 7 char, the 2nd is from 8 to 12 ...
Is it possible?
