安裝maven
http://apache.dataguru.cn/maven/maven-3/3.1.1/source/apache-maven-3.1.1-src.tar.gz
安裝Findbugs
http://ncu.dl.sourceforge.net/project/findbugs/findbugs/2.0.3/findbugs-2.0.3.tar.gz
安裝protobuf
https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.bz2
hadoop2.3.0源碼
http://mirrors.hust.edu.cn/apache/hadoop/common/hadoop-2.3.0/hadoop-2.3.0-src.tar.gz
參考：http://wiki.apache.org/hadoop/HowToContribute
2.解壓源碼，然後用mvn編譯mvn package -Pdist,native,docs -DskipTests -Dtar
二、Hadoop 2.3.0集羣配置
配置項參考：http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/ClusterSetup.html
安裝包下載地址：http://apache.fayea.com/apache-mirror/hadoop/common/hadoop-2.3.0/hadoop-2.3.0.tar.gz
1.jdk配置
2.ssh無密碼登陸
3.配置hdfs-site.xml ,core-site.xml,mapred-site.xml,yarn-site.xml,slaves,yarn-env.sh,haoop-env.sh（jdk位置）
4.啓動hadoop start-dfs.sh start-yarn.sh
附：
hadoop編譯參考：

注：11/09/20 17:29:49 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform… using builtin-java classes where applicable 出現這樣的錯誤
1.指定本地庫的路徑,hadoop-env.sh
export HADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_HOME}/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"
2.庫不兼容本機機器系統，本地maven編譯hadoop項目，將編譯所得的本地庫替換libhadoop.so就可以了。
