hadoop中文镜像地址:http://mirrors.hust.edu.cn/apache/hadoop/core/hadoop-2.2.0/ 第一步,下载
wget 'http://archive.apache.org/dist/hadoop/core/hadoop-2.2.0/hadoop-2.2.0.tar.gz' 第二步,编译haoop-2.2.0(注解:这一步很费时间)
因为官方下载只提供32位的,所以自己编译为64位
http://blog.csdn.net/canlets/article/details/18709969 在Ubuntu 64位OS上运行hadoop2.2.0[重新编译hadoop]
我遇到了与上文作者完全一致的错误:
[INFO] BUILD FAILURE
根据他提供的方法:
目前的2.2.0 的Source Code 压缩包解压出来的code有个bug 需要patch后才能编译。否则编译hadoop-auth 会提示上面错误。
解决办法如下:
修改下面的pom文件。该文件在hadoop源码包下寻找:
hadoop-common-project/hadoop-auth/pom.xml
打开上面的的pom文件,在54行加入如下的依赖:
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-util</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty</artifactId>
<scope>test</scope>
</dependency>
然后重新运行编译指令即可。编译是一个缓慢的过程,耐心等待哦。 至此,应该编译完成
第三步:伪分布式安装
http://my.oschina.net/u/179537/blog/189239 主要参考这个
遇到的问题1:

解决办法是:
vim etc/hadoop/yarn-site.xml
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value> --------注意事项:是mapreduce_shuffle 不是 mapreduce.shuffle
</property>
然后重新启动 hadoop 即可。
遇到的问题2:
root@water:/home/hadoop# sbin/start-dfs.sh
Starting namenodes on [localhost]
localhost: Error: JAVA_HOME is not set and could not be found.
localhost: Error: JAVA_HOME is not set and could not be found.
vim libexec/hadoop-config.sh
找到 JAVA_HOME is not set and could not be found. 这个错误提示的代码,然后在其代码前面定义JAVA_HOME
export JAVA_HOME=/usr/java/jdk
# Attempt to set JAVA_HOME if it is not set
if [[ -z $JAVA_HOME ]]; then
# On OSX use java_home (or /Library for older versions)
if [ "Darwin" == "$(uname -s)" ]; then
if [ -x /usr/libexec/java_home ]; then
export JAVA_HOME=($(/usr/libexec/java_home))
else
export JAVA_HOME=(/Library/Java/Home)
fi
fi # Bail if we did not detect it
if [[ -z $JAVA_HOME ]]; then
echo "Error: JAVA_HOME is not set and could not be found." >&
exit
fi
fi
错误消失
第四步:运行wordcount:
bin/hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/sources/hadoop-mapreduce-examples-2.2.0-sources.jar org.apache.hadoop.examples.WordCount /in /out
