Sandbox

A toy environment for testing.

Deployment

bash deploy.sh This script will prepare the environment to run Nameserver and Chunkservers.

Launch

bash deploy.sh This script will launch Nameserver and Chunkservers to put up a BFS cluster(only it is not a real cluster, but a simulation on one server). Logs will be saved under nameserver0/log and chunkserver[id]/log.

Testing

To create a directory: ./bfs_client mkdir /user

Put a binary to our cluster: ./bfs_client put chunkserver /chunkserver

List a directory: ./bfs_client ls /

Download a file to local fs: ./bfs_client get /chunkserver ./file_from_bfs

Cleanup

To tear down the cluster and cleanup the environment: bash clear.sh

Sandbox

用于DFS的单机部署测试。

部署

bash deploy.sh 会创建Nameserver和Chunkserver运行环境

启动

bash start_bfs.sh 启动Nameserver与多个Chunkserver，形成一个单机（模拟）集群。 日志会被打印在nameserver0/log和chunkserver[id]/log

测试

创建文件夹：
./bfs_client mkdir /user

将chunkserver的二进制作为一个普通文件上传到集群上：
./bfs_client put chunkserver /chunkserver

查看文件：
./bfs_client ls /

将文件下载到本地
./bfs_client get /chunkserver ./file_from_bfs

清理

bash clear.sh
