There is an API in Java. You can use it by including the Hadoop code in your project. The JavaDoc is quite helpful in general, but of course you have to know, what you are looking for *g * http://hadoop.apache.org/common/docs/

For your particular problem, have a look at: http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/fs/FileSystem.html (this applies to the latest release, consult other JavaDocs for different versions!)

A typical call would be: Filesystem.get(new JobConf()).create(new Path("however.file")); Which returns you a stream you can handle with regular JavaIO.
