我基本上是在尝试在远程节点上运行mad reduce作业，我面临下面提到的异常。有人经历过同样的问题吗？我正在发布scipt，我正在使用它设置类路径并启动作业。

# !/bin/bash

export JAVA_HOME=/usr/java/jdk7
export HADOOP_HOME=/usr/local/hadoop/hadoop-2.4.0
export CONF=/home/hadoop/p2Cluster/conf
export PATH=$CONF:$HADOOP_HOME/bin:$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$CONF:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export HADOOP_CONF_DIR=$CONF
echo "classpath=$CLASSPATH"

# 

C2=""
JARS=`find $HADOOP_HOME -name '*hadoop*.jar'`
for j in $JARS
do
echo "$j"
export CLASSPATH=$CLASSPATH:$j
C2=$C2,$j
done

client=******
jobQueueName=default
JAR=****.jar
export HADOOP_CLASS_PATH=$CLASSPATH
hadoop jar $JAR $client  interactive 2 groupA.txt groupB.txt

# 

# java $client  interactive 2 groupA.txt groupB.txt $jobQueueName

exit 0

error:
