下面列出了怎么用org.apache.hadoop.fs.FileSystemContractBaseTest的API类实例代码及写法，或者点击链接到github查看源代码。
@Override
protected void setUp() throws Exception {
Configuration conf = new HdfsConfiguration();
conf.set(CommonConfigurationKeys.FS_PERMISSIONS_UMASK_KEY,
FileSystemContractBaseTest.TEST_UMASK);
cluster = new MiniDFSCluster.Builder(conf).numDataNodes(2).build();
fs = cluster.getFileSystem();
defaultWorkingDirectory = "/user/" +
UserGroupInformation.getCurrentUser().getShortUserName();
}
