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：

14/02/14 09:57:59 INFO mapreduce.Job: Task Id : attempt_1392341518773_0004_m_000000_0, Status : FAILED

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)

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." 1>&2

    exit 1

  fi

fi

错误消失

 

第四步：运行wordcount：

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：
