获取上述错误，使用ubuntu 12.04 32位，我正在使用的java jdk是 java- 6-openjdk-i386 。

Getting the above error , using ubuntu 12.04 32-bit , java jdk I am using is java-6-openjdk-i386.

这里是驱动程序类代码： -

And here is the driver class code :-

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;
import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;
import org.apache.hadoop.mapreduce.task.JobContextImpl;
import org.apache.hadoop.mapreduce.Job;
import org.apache.hadoop.mapreduce.Mapper;
import org.apache.hadoop.mapreduce.Reducer;


        Job baseJob = new Job(conf,"baseJob");//for base itemsets

推荐答案

我遇到了同样的异常。

原因是你的java依赖不完整，你丢失了jar包hadoop-auth-2.2.0.jar或更新的版本。字段IBM_JAVA位于java类PlatformName.class中，该类位于hadoop-auth-2.2.0.jar中的org.apache.hadoop.util包中。

I have met the same exception.
The cause is that your java dependancies are not complete, you have lost the jar package hadoop-auth-2.2.0.jar or its newer version. The field IBM_JAVA is in the java class PlatformName.class, which is in the package org.apache.hadoop.util in hadoop-auth-2.2.0.jar.
