NiFi cluster question

[Igor Kravzov]

If I understand correctly in cluster mode the same dataflow runs on all the
notes.
So let's say I have a simple dataflow with GetTwitter and PutHDFS
processors. And one NCM + 2 nodes.
Does it actually that mean the GetTwitter will be called independently and
potentially simultaneously on each node and there may be duplicate results?
How about PutHDFS processor?  To where "hadoop configuration resources"
"parent HDFS directory" should point to in each node?
