USE CASE- Read files from HDFS,SFTP the files and delete the files from HDFS on successful SFTP .

I am not able to configure the sFTP destination  .It throws validation error .

With the same configuration details ,I was able to configure SFTP as source...The issue persists only around SFTP destination.

I am using Resource URL,Username and Private key to configure it .I am certain that there is no issue with the credentials because it is working with SFTP source .. 

Can you please highlight if SFTP Destination demands something else..
