Interacting with HDFS
Because HDFS is built on top of the Java platform, the majority of
integration and interaction options all require some level of Java
development. Although these options, which range from the HDFS
application programming interface (API) to Apache Thrift, are important
(particularly if you are writing native client interactions), this chapter
introduces only two of those most commonly used on the Microsoft
platform: the HDFS command shell and WebHDFS. This is not intended to
discount the other available options; instead, it is intended to help you get
your feet wet as you get started with HDFS.
Hadoop File System (FS) Shell
Whether you realized it or not, you've already seen the HDFS command
shell in action. As you worked through the Hortonworks Data Platform
On-Premise introduction, the commands used to both upload and retrieve
data from HDFS were all handled by the File System (FS) shell.
