sftp processors start giving SSH_MSG_UNIMPLEMENTED errors after moving to v. 1.16.1

Hi

After migrating out flow from a single instance running version 1.13.2 to
a 3 node cluster running 1.16.1 many of our sftp processors begin to gives
this error: net.schmizz.sshj.transport.TransportException: Received
SSH_MSG_UNIMPLEMENTED

Servers are running Ubuntu 20.04, both NIFI and sftp servers.

Any idea why?
I have tried to debug it, but have not been able to find any reasons. I've
changed the processors to only have 1 concurrent task instead of old
settings with 3-5 since we also change from single instance to cluster.

Kind regards
Jens M. Kofoed

Hi Jens,

Thanks for reporting this problem, can you open a Jira issue?

https://issues.apache.org/jira/browse/NIFI

If you can provide a full stack trace, that would be helpful. It would also
be helpful to know what strategy you are using for authentication: are you
using a private key or a password?

Setting the log level to DEBUG for the net.schmizz.sshj logger should also
provide additional details.

Regards,
David Handermann
