I have downloaded hadoop tools for ArcMap and installed. In the ArcToolboxe window the hadoop tools are displayed. In the hadoop toolbox the "Copy from HDFS" tool is asking for an HDFS server hostname, TCP port number, username and remote file. I'm having hard time getting these right. Please tell about the values to be typed in the host name, username and port number. I'm using "Cloudera VMWare" for analyzing the data using hive queries.
If you have not seen the front page of the project, that gives an overview of the project, as well as listing blog and video resources at the bottom.
There are also a few issues on GitHub that may help you troubleshoot any problems that you encounter.
Full disclosure, I work on this project.
