java - 启动MiniDFSCluster时出错

转载作者：行者123 更新时间：2023-12-02 20:45:17

我已经遇到一个问题已经有一段时间了，我没有解决这个问题的主意...

我正在尝试为将在Hadoop上运行的Java代码开发单元测试。为此，我试图根据网络使用MiniDFSCluster，这是在单元测试hadoop Java代码中最常用的方法。

当我在团队中工作时，我想创建一个“母类”，其目的是建立MiniDFSCluster。每个需要使用mini cluser的测试类都将扩展该类，并且每个开发人员都可以在需要时对hadoop代码进行单元测试。

为了上述目的，我写了这个“母类”:

package com.sncf.setup;

import static org.junit.Assert.assertNotNull;

import java.io.File;

import org.apache.hadoop.conf.Configuration; 
import org.apache.hadoop.fs.FileUtil;
import org.apache.hadoop.hdfs.DistributedFileSystem;
import org.apache.hadoop.hdfs.MiniDFSCluster;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;


public class SetupMiniCluster {

protected static MiniDFSCluster hdfsCluster ; 

protected static File baseDir ; 

protected static DistributedFileSystem fileSystem ; 

protected static String hdfsURI ; 

@BeforeAll
private static void setUpBeforeClass() throws Exception {

    baseDir = new File("./target/hdfs").getAbsoluteFile();
    Configuration conf = new Configuration();
    conf.set(MiniDFSCluster.HDFS_MINIDFS_BASEDIR, baseDir.getAbsolutePath());
    MiniDFSCluster.Builder builder = new MiniDFSCluster.Builder(conf);
    hdfsCluster = builder.numDataNodes(3).build();
    hdfsURI = "hdfs://localhost:"+ hdfsCluster.getNameNodePort() + "/";
    fileSystem = hdfsCluster.getFileSystem();
}

@Test
void testNotNull() {
    assertNotNull(hdfsURI);
    assertNotNull(baseDir);
    assertNotNull(fileSystem);
}

@AfterAll
private static void tearDownAfterClass() throws Exception {
    hdfsCluster.shutdown();
    FileUtil.fullyDelete(baseDir);
}

}

当我以JunitTest(与Junit 5一起)运行此类时，最终得到以下堆栈跟踪:

如果有人有解决方案或至少有解决该问题的线索，将不胜感激:)

谢谢
