This project aims to be a complete implementation of a Java7/NIO.2 File System Provider backed by GlusterFS via libgfapi-jni
Please let me know if you use this project, even if you're just checking it out, I'd like to hear from you.
I prefer to be contacted on IRC, Twitter, or a Github issue. You can find me, semiosis, in #gluster on Freenode IRC. My twitter handle is @pragmaticism.
Thanks!

The maven shade plugin can build a unified (shaded) JAR suitable for dropping in to the classpath of any JVM application.
You can build a "shaded" JAR by cloning the project and running the following command in the glusterfs-java-filesystem subdirectory:
cd glusterfs-java-filesystem
mvn package shade:shade
Maven will report the path of this shaded JAR. You can run export CLASSPATH=<path-to-shaded.jar> in a terminal before running your other application.
Contact me (on IRC, Twitter, or in a Github issue) if you need help obtaining a JAR, if you can't, or don't want to, build it with maven yourself.
Once this library is in your classpath all you need to do in your code is access a GlusterFS URI, for example
gluster://server:volume/path
A Vagrantfile in the root of this repository sets up a VM with a volume called foo at IP address 172.31.31.31 on a private network.
The Example.java file in the glusterfs-java-filesystem-example project provides a demonstration of the capabilities of this project from a high level consumer's point of view, it connects to the volume on the vagrant VM.
To run:
cd glusterfs-java-filesystem-example
vagrant up
mvn exec:exec
- Replace Example program with formal integration test suite
- Align project versions with glusterfs (this project & libgfapi-jni)
- Update watch service to use libgfchangelog (instead of polling)
- Finish attribute support
Owner/group names & ability to change
More ways to set permissions - Finish integration testing for advanced synchronous file IO (reading/writing portion of file)
- Asychronous file I/O
- Better error reporting & handling (utilize UtilJNI.strerror() as part of IOException throws)
- Finish readSymbolicLink unit tests
- Publish test coverage report to Coveralls.io
Blocked due to use of Atlassian Clover - Create hard links
- Connect to a GlusterFS volume using the NIO.2 API
- Basic synchronous file I/O
Read the contents of a file all at once
Write a chunk of bytes to a file all at once - File attributes
See owner/group id, size, permissions, and last modified timestamp on files and directories
Set permissions - Filesystem/volume stats
See the total, free, and usable bytes in a volume - Directory listing (with filtering)
- Move/rename files
- Watch files for changes
Complete except for GlusterWatchKeyTest, in progress - Create & Read symlinks (read tests incomplete)
- Publish test coverage & code quality reports to SonarQube
- Delete files
- Copy files
- Advanced synchronous file IO
