[待解决问题]
我是个新手，在linux使用java编程时，出现这个情况。
我把要引的包放在classpath中，红色部分：
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$HADOOP_HOME/hadoop-1.0.4.core.jar:${CLASSPATH}
通过echo $CLASSPATH查看也能输出结果。
mport org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.io.Text;
import org.apache.hadoop.mapreduce.Job;
import org.apache.hadoop.mapreduce.Mapper;
import org.apache.hadoop.mapreduce.Reducer;
import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;
import org.apache.hadoop.mapreduce.lib.output.FileOutputFormat;
public class wordcount {
public static class WordCountMapper extends Mapper<Object, Text,Text,IntWritable>
{
private final static IntWritable one=new IntWritable(1);
private Text word=new Text();
public void map(Object key, Text value,Context context) throws IOException,InterruptedException{
String[] words=value.toString().split(" ");
for(String str : words)
{
word.set(str);
context.write(word,one);
}
}
}
public static class WordCountReducer extends Reducer<Text,IntWritable,Text,IntWritable>{
public void reduce(Text key,Iterable<IntWritable> values,Context context) throws IOException,InterruptedException
{
int total =0;
for(IntWritable val1 : values)
{
total++;
}
context.write(key,new IntWritable(total));
}
}
public static void main(String[] args) throws Exception {
Configuration conf1=new Configuration();
Job job=new Job(conf1,"word count");
job.setJarByClass(wordcount.class);
job.setMapperClass(WordCountMapper.class);
job.setReducerClass(WordCountReducer.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(IntWritable.class);
FileInputFormat.addInputPath(job, new Path(args[0]));
FileOutputFormat.setOutputPath(job, new Path(args[1]));
System.exit(job.waitForCompletion(true ) ? 0:1);
}
}
使用javac wordcount.java 编译出现：

，我想问下这个引用第三方的jar包，如何使用啊？急

windows下如下 最后一个;后面必须要用空格把这个类和lib包分开。LZ是在linux下，需要把;替换成：路径当然也要替换成linux格式的。
javac -cp c:\abc.jar;d:\efg.jar; f:\Test.java
java -cp c:\abc.jar;d:\efg.jar; f:\Test
