HDFS Connector

This node connects to a Hadoop Distributed File System using HDFS, WebHDFS or HTTPFS. The resulting output port allows downstream nodes to access the files of the remote file system, e.g. to read or write, or to perform other file system operations (browse/list files, copy, move, ...).

Path syntax: Paths for HDFS are specified with a UNIX-like syntax, /myfolder/myfile. An absolute for HDFS consists of:

  1. A leading slash ("/").
  2. Followed by the path to the file ("myfolder/myfile" in the above example).

SSL: This node uses the JVM SSL settings.



HDFS protocol to use.
Address of HDFS name node or WebHDFS/HTTPFS node.
Use the default or a custom port to connect to HDFS name node or WebHDFS/HTTPFS node.

Note: The WebHDFS default ports are the Hadoop 3.x default ports. The default WebHDFS port on Hadoop 2.x is 50070 and 50470 with SSL.
  • Username: Pseudo/Simple authentication using a given username.
  • Kerberos: Kerberos ticket based authentication.
Working directory
Specify the working directory of the resulting file system connection, using the Path syntax explained above. The working directory must be specified as an absolute path. A working directory allows downstream nodes to access files/folders using relative paths, i.e. paths that do not have a leading slash. The default working directory is the root "/", under which all the document libraries are located.
