Yes, it was resolved. But I don't have a good explanation. It actually resolved itself by simply restarting the NiFi process on all nodes. After the restart they all connected and worked as expected.
Interesting. I performed several restarts and kept receiving the error "Unable to obtain password from user". I then decided to perform a full stop, wait a couple minutes, then start (I have 2 NiFi nodes) and now its working. Very strange...

I had the exact same issue and tried bringing down both of my two NiFi nodes, waiting a few minutes, and brought them back online. Then I tried turning on the PutHDFS processor and it worked properly.
Has anyone figured out why this solves the issue or what is causing this problem?
