SFTP CLI works but PutSFTP fails

@nisaar 

When you execute the SFTP CLI, are you doing so as the same user that owns the running NiFi process?  If not, switch to teh NiFi service user and then try your SFTP CLI command again to see if it is successful or if it ask you to accept the host key for the SFTP target.  If you are asked to accept the host key, try running your NiFi putSFTP processor again after you accept the host key on the NiFi service user account.

It does not matter what user is authenticated in NiFi or which user created the dataflow on the NiFi canvas.  All components are executed as the NiFi service user.

We have deployed NiFi as docker image on Virtual Machine.

From VM CLI SFTP command connects with root user.

On logging in to docker container using docker exec -it <id> bash,

there is no sftp command available to test.

Thanks You
