List/fetch ftp/sftp processors problem

Re: List/fetch ftp/sftp processors problem

Hello @Oleksandr Solomko

Sorry to hear that you had an issue with FTP processors.

Would you elaborate the symptoms so that we can diagnose better? When you said "ftp/sftp processors don't work", do you see a number (usually 1 or 2) at the right top corner of the processor keeps being shown? If so, the processor may be stuck at some point while NiFi scheduler executes it. In this case, NiFi thread dump will be informative to nail down what the processor is doing or where it gets stuck. To take thread dump, please execute following command:

${NIFI_HOME}/bin/nifi.sh dump

Then Java stack trace will be logged into logs/nifi-bootstrap.log.

It seems the logs you shared previously are ones that were logged when you stopped ListFTP processor (excuse me if I'm wrong). I found this log particularly interesting, this message looks like ListFTP was in the middle of doing something when it's told to stop.

2017-06-12 13:50:46,803 ERROR [Timer-Driven Process Thread-17] o.a.nifi.processors.standard.LisFTP ListFTP[id=0b26dd50-015c-1000-ab83-c3df49136530] ListFTP[id=0b26dd50-015c-1000-ab83-c3df49136530] failed to process due to java.lang.IllegalStateException: Partition is closed; rolling back session: java.lang.IllegalStateException: Partition is closed

Thread dump would be helpful to know what is happening. Please run nifi.sh dump while ListFTP is running (and seems not working, before shutting NiFi process down), and share nifi-bootstrap.log with us if possible.

Thanks,

Koji

Re: List/fetch ftp/sftp processors problem

Thanks for sharing updates. I didn't find anything suspicious in bootstrap log. The error message indicates there are some network issue between NiFi node and FTP server.

filename /edb4tel/data/DMP/TIAGPRSVMPT063246 on remote host 172.30.129.1:21 due to java.net.SocketTimeoutException: Read timed out

Can you confirm NiFi node can access to the FTP server port 21? Using telnet command, you can check connectivity:

$ telnet 172.30.129.1 21
(If successfully connected, the response from FTP server will be shown)

Re: List/fetch ftp/sftp processors problem

Nifi node can access to FTP server port. Telnet, ftp-command line..... all ok....

Re: List/fetch ftp/sftp processors problem

Thanks for trying. I haven't been able to reproduce the Read timed out issue. ListFTP/SFTP, GetFTP ... etc just work fine in my environment. I confirmed that it can download large file about 1GB.

There's another user facing the same issue, though..

https://community.hortonworks.com/questions/107715/nifi-130-getftp-read-timed-out.html

Did you try other FTP servers, just to confirm if the issue is FTP server specific. For example, a public FTP server such as the one to be used to download apache binaries, http://www.apache.org/dyn/closer.cgi/httpd/binaries/

If those processors work with other FTP servers, then I'd suggest looking at the FTP server's log as well.

Re: List/fetch ftp/sftp processors problem

ListFTP-processor gives us list of files from remote srver and then FetchFTP returns "Read timed out" error

Hello, I am facing the same issue. ListFTP works fine but FetchFTP gives me Read Timed Out exception. Did you find a solution? I would be very appreciated.
