how to use listftp processor?

[#1]

I want to monitoring directory in ftp server becuase files were sometimes changed and added.

I added ListFTP processer and then execute.

I want to get file list repeatly and diff filename and modification date however listftp was only one time execute. It wasn't execute again.

please advices me what to do.

How was the ListSFTP processor scheduler set? See this doc for scheduling: https://docs.hortonworks.com/HDPDocuments/HDF1/HDF-1.2/bk_UserGuide/content/scheduling-tab.html

Suggestion is to have it every 5 sec or so.

Let me know how it goes.

I changed Run Schedule but it wasn't execute again.

what should I check?

Are you using DistributedMapCache along with ListSFTP?

Same file won't be listed by ListSFTP and that may be reason to think it executed only once. If you just "touch" existing file then it is again listed. If there is continuous feed of different files then ListSFTP will list all new files coming into directory.

when new file added to ftp. it modification date is before listing.timestamp
