							 You can use PutHDFS or FetchHDFS depending on your using. You need to set the properties Hadoop Configuration Resources in the processor which you can point to the location where you have core-site and hdfs-site configuration files. Make sure network connections are OK between NiFi and HDP. Also didnt understand your usecase fully, "Why you would like to use NiFI to copy files between HDFS directories?"

							 Just added relevant lines here.  public static final Relationship SUCCESS = new Relationship.Builder().name("SUCCESS")  .description("Success relationship").build();  if (msgText != null) {  FlowFile flowFile = session.create();  flowFile = session.write(flowFile, new OutputStreamCallback() {  public void process(final OutputStream out) throws IOException {  try {  out.write(msgText.getText().getBytes());  } catch (Exception e) {  e.printStackTrace();  }  }  });  session.getProvenanceReporter().receive(flowFile, context.getProperty("MyProp").getValue());  session.transfer(flowFile, REL_SUCCESS);  }  queueConn.close();  session.commit();
