Please provide the full error from NIFI_HOME/logs/nifi-app.log.

Re: Nifi putHDFS Error

There has to be more logs than this... anything that shows as an error in the NIFI UI will be somewhere in nifi-app.log with an ERROR or WARN logging statement.

Can you try "grep ERROR nifi_home/logs/*" to see where the error is in the logs?

Do you have the necessary ports open to communicate with the HDP cluster?
