Question

我看到很多关于这个问题的引用，我已经发布了here

我正在使用Hadoop 2.4.1和Flume 1.5.0.1。我的flume-env.sh配置如下

FLUME_CLASSPATH="/var/lib/apache-flume-ng:lib/hadoop-core-1.2.0.jar:lib/hadoop-auth-2.4.1.jar:lib/hadoop-yarn-api-2.4.1.jar:lib/hadoop-mapreduce-client-jobclient-2.4.1.jar:lib/hadoop-mapreduce-client-core-2.4.1.jar:lib/hadoop-common-2.4.1.jar:lib/hadoop-annotations-2.4.1.jar"

使用这些罐子我已经在Flume的lib中添加了另外一个jar，它是commons-configuration-1.6.jar。我是Flume和Hadoop的新手。

完整跟踪如下：

Answer 1

问题是由缺少或冲突的依赖项引起的：

将hadoop-auth添加到您的类路径
如果问题仍然存在，请从类路径中删除hadoop-core。它与hadoop-auth相冲突。

这将解决问题。

Answer 2

最后我找到了答案。

从hadoop-auth复制PlatformName类并在本地自定义编译。

package org.apache.hadoop.util;

公共类PlatformName {

    private static final String platformName = System.getProperty("os.name") + "-" + System.getProperty("os.arch") + "-" + System.getProperty("sun.arch.data.model");

    public static final String JAVA_VENDOR_NAME = System.getProperty("java.vendor");

    public static final boolean IBM_JAVA = JAVA_VENDOR_NAME.contains("IBM");

    public static String getPlatformName() {
        return platformName;
    }

    public static void main(String[] args) {
        System.out.println(platformName);
    }
}

将类文件复制粘贴到hadoop-core中。你应该开始运作。
