ucz-dfs (ucz distributed file system)

A distributed file system, based on hdfs/gfs. Just for fun and learning.

Work is still in progress, a lot of things are missing.

If you want to try it out, the easiest way it to spin up docker containers (docker-compose up), and bash into a running container (docker exec -it <id> bash).

Inside a running container, you can:

1. List datanodes shell report
2. ls shell ls /
3. mkdir shell mkdir /foo/bar/baz
4. Upload a file shell put build.rs /build.rs
5. Download a file shell get /build.rs ./temp

To spin up nodes yourself:

Spin up a namenode

UDFS_CONFIG_FILE=/path/to/config.toml cargo run --bin namenode

Spin up a datanode

UDFS_CONFIG_FILE=/path/to/config.toml cargo run --bin datanode localhost:42001
