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

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 Container launch failed for container_1392341518773_0004_01_000002 : org.apache.hadoop.yarn.exceptions.InvalidAuxServiceException: The auxService:mapreduce_shuffle does not exist at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at org.apache.hadoop.yarn.api.records.impl.pb.SerializedExceptionPBImpl.instantiateException(SerializedExceptionPBImpl.java:152) at org.apache.hadoop.yarn.api.records.impl.pb.SerializedExceptionPBImpl.deSerialize(SerializedExceptionPBImpl.java:106) at org.apache.hadoop.mapreduce.v2.app.launcher.ContainerLauncherImpl$Container.launch(ContainerLauncherImpl.java:155) at org.apache.hadoop.mapreduce.v2.app.launcher.ContainerLauncherImpl$EventProcessor.run(ContainerLauncherImpl.java:369) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744)
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：
bin/hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/sources/hadoop-mapreduce-examples-2.2.0-sources.jar org.apache.hadoop.examples.WordCount /in /out

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：
