Lightweight distributed file system implemention in java

We are working on an JavaEE application where user can upload images,videos(usually a zip contains a lot of small files) to the server, generally we will save the file(files) to a certain local directory, and then user can access them.

But things get complicated once the application is deployed on multiple servers in front of which a load balance resides. Say there are two servers Server1 and Server2, and one user try to upload some files, and this request is dispatched to Server2, nothing wrong here. And later, another user try to access the file, and his request is dispatched to Server1, then the application can not find the file.

Sounds like I need a distributed file system, while I only need a few features:

1)Nodes can detect each other by themselves.
2)read and write file/directory
3)unzip archive
4)automatically distributes data based on the available space of nodes

HDFS is too big for my application, and I does not need to process the data, I only care about the storage.

Is there a java based lightweight alternative solution which can be embedded in my application?

I'd probably solve this at the operating system level using shared network attached storage. (If you don't have a dedicated NAS available, you can have an application server act as NAS by sharing the relevant directory with NFS).
