HDInsight hadoop java程序無法運行 - 找不到庫

在W7上安裝Haddop HDInsight之後。無法編譯具有hadoop特定實現的java程序。他們出錯誤說：HDInsight hadoop java程序無法運行 - 找不到庫

c:\Hadoop\hadoop-1.1.0-SNAPSHOT\bin>javac -classpath `C:\Hadoop\hadoop-  1.1.0-SNA 
    PSHOT\hadoop-core.jar` C:\Z\WordCount.java -d C:\Z

               ^
     symbol: class MapReduceBase 
     location: class WordCount 
    C:\Z\WordCount.java:14: error: cannot find symbol 
       public static class Map extends MapReduceBase implements Mapper<Long

    C:\Z\WordCount.java:14: error: cannot find symbol 
       public static class Map extends MapReduceBase implements Mapper<Long 
    Writable, Text, Text, IntWritable> { 
                       ^

起初，我試着做

的javac C：/z/WordCount.java

，然後也嘗試

c:\Hadoop\hadoop-1.1.0-SNAPSHOT\bin> 
    javac -classpath `C:\Hadoop\hadoop-1.1.0-SNAPSHOT\hadoop-core.jar` 
    C:\Z\WordCount.java -d C:\Z

即，給人一種類路徑。

嗯，我不知道到哪兒點的javac

這是我在我的Hadoop文件夾：

請指教。

在哪裏Hadoop的core.jar添加？ –

它被列爲上述罐子之一。列表中部 – ZeExplorer

嘗試使用下面的類路徑：

-classpath％HADOOP_HOME％\ Hadoop的核心1.1.0-SNAPSHOT.jar;％HADOOP_HOME％\ LIB \公地CLI-1.2.jar

當我使用以下命令時，能夠編譯： 'javac -classpath％hadoop_home％\ hadoop-core-1.1.0-SNAPSHOT.jar;％hadoop_home％\ lib \ commons-cli-1.2。 jar C：\ Z \ WordCount.java' – ZeExplorer

但無法編譯， 'java wordcount'給出ClassDefNotFound錯誤 'java -cp（與編譯相同）WordCount' 給出無法找到或加載主類。有什麼建議麼。 – ZeExplorer
