start.dfs.sh中的異常

我使用hadoop設置了兩個節點羣集。start.dfs.sh中的異常

當我運行start-dfs.sh我得到這個錯誤：

starting namenode, logging to /usr/local/hadoop/bin/../logs/hadoop-hadoop-namenode-mohit-ubuntu.out 
slave: starting datanode, logging to /usr/local/hadoop/bin/../logs/hadoop-hadoop-datanode-balaji-ubuntu.out 
slave: Exception in thread 「main」 java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName

master: starting secondarynamenode, logging to /usr/local/hadoop/bin/../logs/hadoop-hadoop-secondarynamenode-mohit-ubuntu.out

收到這個錯誤，我改變了HADOOP_CLASSPATH到export HADOOP_CLASSPATH=${HADOOP_CLASSPATH}:$HADOOP_HOME/lib/commons*.jar:$HADOOP_HOME:$HADDOP_HOME/hadoop-core-0.20.203.0.jar:$HADOOP_HOME/conf

之後，但它並沒有幫助。

請參閱以下堆棧溢出問題。我在那裏回答了這個問題 http://stackoverflow.com/questions/13183164/hadoop-error-can-not-start-all-sh/14932469#14932469 – abhinav 2013-02-20 06:30:01

這種類似於jar文件不存在於從節點上。從站的安裝或配置可能不正確。

或者你可以查看我的博客，我已經解釋了它。還張貼您的配置文件，以便我們可以調試它們。 http://blog.abhinavmathur.net/2013/01/adding-more-nodes-to-hadoop-cluster.html
