Rather than GetFile, you could use ListenHttp -> FetchFile -> PutHDFS. Then you can POST to your configured endpoint with a header set to the filename, and in ListenHttp set that header name as the value of the "HTTP Headers to receive as Attributes (Regex)" property. Then FetchFile would be configured to use that attribute to fetch the file and pass to PutHDFS.

Hi @Matt Burgess, how can we do thos for a csv file..?

for example i am having a csv file(studentid_name_city.csv). I want to break the filename and put it into different columns of Studend table(Studentid,name,city).
