JAVA_HOME 已经配置了 [root@hnd1 bin]# java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
[root@hnd2 libexec]# java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
[root@hnd3 ~]# java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
hadoop-1.2.1/libexec/这个文件 是什么 ？ 我安装后没有这个目录
为什么用的是1.2的?
还有就是环境变量HADOOP_HOME要设置.2.x的应该是HADOOP_INSTALL JAVA_HOME问题直接改hadoop-x.x.x/etc/hadoop/hadoop-env.sh 里的JAVA_HOME
使用hadoop+中文分词统计小说里的用词频率
Eclipse如何关联Hadoop的源码
多谢了，已经解决
路径 使用了软连接，这个路径是对的
但是对应的实际路径不对 以为软连接上修改了就行
建议你参考厦门大学数据库实验室里的教程：http://dblab.xmu.edu.cn/，里面的bllog板块有详细的配置步骤...
