@Juthika Shenoy

Have you manually tried to sftp to the remote system using the private key from the command line of the system running NiFi? Usually, the first time you connect to a system you are prompted to accept the key.

Yes - I have tried that , I am prompted for the passphrase and I have provided the same in the configuration

I had issues with the PutSFTP processor(though using nifi 1.2.0) due to some authentication error, strange thing is that I created custom PutSFTP processor and it works.

Other user experienced similar issue http://apache-nifi-developer-list.39713.n7.nabble.com/NIFI-PutSFTP-Auth-Fail-td15236.html.

Kind of sucks that Jsch is horrible for end user to configure logging. The codebase of 1.2 has a class called SFTPUtils which does configure a logger for jsch, but looks like the PutSFTP processor itself is not using the SFTPUtils class and nor has a jsch logger configured.

 I am having a simple flow where I am fetching the creds for SFTP from DB and then uploading a file using the putSFTP but I am getting UnknownHostException error on PutSFTP processor.

I see the creds are being fetched - I see them in logs and also tried connecting to the Server using FileZilla (creds are correct ..no space etc all good with that)..

Also I tried hardcoding the creds in PutSFTP and still it did not work.

can someone please guide me..
