我编写java代码，将csv文件转换为向量，以便在使用随机林算法的分类任务中使用。我使用mahout 0.10.0、hadoop 2.6.0和eclipse。然后，我尝试使用该命令从cmd运行以下代码：

hadoop jar /path to my jar/CSVToVector.jar com.classification.csvtovector.CSVToVector

但我有个错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/mahout/math/Vector

.bash\u配置文件包含以下内容：

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home
export PATH=$PATH:$JAVA_HOME/bin
export HADOOP_PREFIX=/Users/jooody/hadoop
export HADOOP_HOME=$HADOOP_PREFIX

export MAHOUT_CONF_DIR=/Users/jooody/mahout/src/conf
export M2_HOME=/Users/jooody/maven/apache-maven-3.2.5
export PATH=$PATH:$M2_HOME/bin

我需要做什么来解决这个问题？我对mahout和hadoop还不熟悉。
