I would like to share one of my projects that I am working on in my PhD.
Since I am working on Big Data I wrote a library to access the Hadoop Distributed File System (HDFS).
We implemented it as a FileSystem in Pharo, using the webHDFS API of HDFS to access the files.
With this API you can browse the distributed file system and create/modify/delete directories and files.
Here is the git repository:
Documentation is in the readme.
