hadoop2.2.0 单机伪分布式（含64位hadoop编译） 及 eclipse hadoop开发环境搭建

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：

// :: INFO mapreduce.Job: Task Id : attempt_1392341518773_0004_m_000000_0, Status : FAILED
Container launch failed for container_1392341518773_0004_01_000002 : org.apache.hadoop.yarn.exceptions.InvalidAuxServiceException: The auxService:mapreduce_shuffle does not exist

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:)
    at java.lang.Thread.run(Thread.java:)

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

// :: INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:

运行结果：

root@water:/home/hadoop# bin/hdfs dfs -cat /out/*
hadoop    1
hello    2
world    1

附加：hadoop启动的一些相关命令

启动namenode
sbin/hadoop-daemon.sh start namenode
sbin/hadoop-daemon.sh start datanode
关闭namenode
sbin/hadoop-daemon.sh stop datanode
sbin/hadoop-daemon.sh stop namenode

http://127.0.0.1:8088/  可以访问hadoop管理页面   hadoop job管理界面
http://127.0.0.1:50070 可以访问namenode节点信息。 可以查看各节点的文件 browser file system

这个异常的解决可以 启动完hbase，不关闭，然后再启动一次hbase 就可以。。。。。奇怪  参考连接：
