How to provide the path in NiFi FetchFile processor

rbnaveen_kumar — Thu, 15 Dec 2016 19:39:55 GMT

I have few files as follows.

/a/b/c/1.txt

/a/b/c/2.csv

/a/b/c/3.csv.gz

I need to fetch all these files using FileFetch processor. What should be the expression in the 'File To Fetch' property?

You should place a ListFile processor in front of you FetchFile.

Alternatively, you could use GetFile, with these properties:

Input Directory: /a/b/c

File Filter: [^\.].* (or change regex if you are filtering specific files by filename pattern)

Note that GetFile does not have the configuration to move the file after processing (creating flowfile)

@NAVEEN KUMAR I would post that as a separate question, since it is different from the question you posed. (You will also get more exposure)
