Question

我想在julia中使用HDFS.jl。但是，每次我输入命令
hdfs_connect("localhost",9000)发生错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/conf/Configuration   Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.conf.Configuration

 in hdfs_connect at /home/gxx/.julia/v0.3/HDFS/src/hdfs_dfs.jl:30

我的hadoop版本是1.2.1，我的类路径是：

export HADOOP_HOME=/home/gxx/usr/hadoop/hadoop-1.2.1
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$HADOOP_HOME/*.jar:$HADOOP_HOME/lib/*.jar:$HADOOP_HOME/hadoop-core-1.2.1.jar

This is the link of HDFS.jl

如何解决？

hdfs_connect（＆＃34; localhost＆＃34;，9000）导致＆＃34; java.lang.NoClassDefFoundError：org / apache / hadoop / conf / Configuration＆＃34;错误
