Hi Geoffrey, Thank you very much. The problem is solved. I found that 50010 port (data transfer port to the HDFS Datanode ) is not added to HDP docker container. But the 50070 port (port to the HDFS namenode) is added. So I can read the metadata of Files in HDFS with the ListHDFS processor but can not get from HDFS and put files to HDFS with the two processors. I am using VirtualBox HDP sandbox, so I still use the default NAT network but changed the IP addresses to the current localhost IP at the setting of Port forwarding. And access to docker host terminal: root@sandbox-hdp.hortonworks.com 2200 Modified the sandbox proxy file generate-proxy-deploy-script.sh (/sandbox/proxy) Add 50010 port as follow, then run the shell program, ./ generate-proxy-deploy-script.sh, Then the proxy-deploy program is updated; Then run the shell (./proxy-deploy.sh) to generate a proxy container and start it (docker start sandbox-proxy).

Hi Geoffrey, Thank you for your reply. Yes, I added these two files in NiFi. So ListHDFS processor in NiFi is able to show the list of files in HDFS. But PutHDFS can not put files in HDFS. I guess that the communication between NiFi and the namenode is ok, but something wrong between NiFi and the datanode. I can not know what configurations would affect that.
