PutHDFS is failing with error 'failed to properly initialize processor'

[#1]

Hello,

I am using putHDFS to upload data from my local machine but it is failing with error 'failed to properly initialize processor';

I am using HortonWorks sand box virtual machine (set up on my local laptop) and nifi is configured on my local laptop (not on VM).

Note: PutSFTP is working on same setup.

Can you share the stack trace from nifi-app.log that goes along with the error?
