hadoop2.2.0源代碼編譯

1、環境說明

虛擬軟件:VMware Workstation 10

虛擬機配置:

RHEL Server release 6.5 (Santiago) 2.6.32-431.el6.x86_64

cpu:4核心,內存:4G,硬盤:50G

2、前提條件:

1:將rhel6.5的iso文件做爲yum源

2:hadoop-2.2.0-src.tar.gz

3:安裝JDK 1.6.0_43

4:安裝並配置apache-maven 3.0.5(apache-maven-3.0.5-bin.tar.gz)

源碼中BUILDING.txt中要求使用3.0，從hadoop2.0版本之後使用maven編譯，以前用Ant)

解壓並配置環境變量

mvn -version

5:安裝並配置apache-ant-1.9.3-bin.zip（下載二進制版本的,這個須要編譯安裝findbugs)

解壓並配置環境變量

ant -version

6:下載並安裝cmake cmake-2.8.12.1,安裝命令以下:

  tar -zxvf cmake-2.8.12.1.tar.gz

  cd cmake-2.8.12.1

  ./bootstrap

  make

  make install

  檢查安裝是否正確

cmake --version(若是能正確顯示版本號,則說明安裝正確)

7:下載並安裝配置findbugs-2.0.2-source.zip

http://sourceforge.jp/projects/sfnet_findbugs/releases/

使用ant編譯安裝。若是不編譯安裝則編譯的時候會報

hadoop-common-project/hadoop-common/${env.FINDBUGS_HOME}/src/xsl/default.xsl doesn’t exist. -> [Help 1]

進入到解壓後的目錄，直接運行ant命令

若是不安裝,則在編譯時會報以下錯誤:

Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (site) on project hadoop-common: An Ant BuildException has occured

8:安裝zlib-devel

默認狀況下,系統沒有安裝zlib-devel

yum install zlib-devel

若是不安裝,則在編譯時會報以下錯誤:

Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (make) on project hadoop-common

9: protobuf-2.5.0

yum install gcc-c++ (若是不安裝,則cmake configure失敗)

./configure

make

make check

make install

檢查安裝是否正確

protoc --version((若是能正確顯示版本號,則說明安裝正確)

3、hadoop2.2源碼編譯

1：進入hadoop2.2.0解壓後的源碼目錄

2：執行mvn命令編譯，此過程須要鏈接網絡，編譯的速度取決於你的網速

mvn clean package -Pdist,native -DskipTests -Dtar

2.1.Create binary distribution without native code and without documentation:

$ mvn package -Pdist -DskipTests -Dtar

2.2.Create binary distribution with native code and with documentation:

$ mvn package -Pdist,native,docs -DskipTests -Dtar

2.3.Create source distribution:

$ mvn package -Psrc -DskipTests

2.4.Create source and binary distributions with native code and documentation:

$ mvn package -Pdist,native,docs,src -DskipTests -Dtar

2.5.Create a local staging version of the website (in /tmp/hadoop-site)

$ mvn clean site; mvn site:stage -DstagingDirectory=/tmp/hadoop-site

3：編譯後的項目發佈版本在hadoop-2.2.0-src/hadoop-dist/target/目錄下

hadoop-2.2.0-src/hadoop-dist/target/hadoop-2.2.0/

4、安裝hadoop 單點僞分佈式模式

1：配置ssh互信

ssh-keygen -t dsa （或行ssh-keygen -t rsa -P "" 加上-P ""參數只須要一次回車就能夠執行完畢。不加須要三次回車）

cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys 

若是仍然須要輸入密碼，則執行以下命令

chmod 600 ~/.ssh/authorized_keys

2：將編譯後的hadoop-2.2.0-src/hadoop-dist/target/hadoop-2.2.0複製到/data/hadoop/目錄下

3：建議軟連接 ln -s hadoop-2.2.0 hadoop2

4: 在用戶的.bash_profile增長以下變量

export HADOOP_HOME=/data/hadoop/hadoop2

export PATH=$PATH:$HADOOP_HOME/bin

export PATH=$PATH:$HADOOP_HOME/sbin

export HADOOP_MAPRED_HOME=${HADOOP_HOME}

export HADOOP_COMMON_HOME=${HADOOP_HOME}

export HADOOP_HDFS_HOME=${HADOOP_HOME}

export YARN_HOME=${HADOOP_HOME}

5:建議data.dir及namenode.dir目錄

mkdir hdfs

mkdir namenode

chmod -R 755 hdfs

6:修改hadoop-env.sh

export JAVA_HOME=/usr/java/jdk1.6.0_43

export HADOOP_HOME=/data/hadoop/hadoop2

7:修改core-site.xml,hdfs-site.xml,mapred-site.xml,yarn-site.xml，內容見附錄2

8：格式化HDFS文件系統

執行命令 hadoop namenode -format

9：啓動hdfs,yarn

start-dfs.sh

start-yarn.sh

10:驗證啓動是否成功

jps

若是顯示以下6個進程，則啓動成功

53244 ResourceManager

53083 SecondaryNameNode

52928 DataNode

53640 Jps

52810 NameNode

53348 NodeManager

5、運行自帶的wordcount例子

hadoop fs -mkdir /tmp

hadoop fs -mkdir /tmp/input

hadoop fs -put /usr/hadoop/test.txt /tmp/input

cd /data/hadoop/hadoop2/share/hadoop/mapreduce

hadoop jar hadoop-mapreduce-examples-2.2.0.jar wordcount /tmp/input /tmp/output

若是能正確運行，則hadoop安裝配置正確

6、附錄1：

設置的環境變量（/etc/profile,編輯後運行source /etc/profile/ 使配置生效）

#java set

export JAVA_HOME=/usr/java/jdk1.6.0_43

export JRE_HOME=/usr/java/jdk1.6.0_43/jre

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export PATH=$PATH:$JAVA_HOME/bin

#maven set

export M2_HOME=/home/soft/maven

export PATH=$PATH:$M2_HOME/bin

#ant

export ANT_HOME=/home/soft/apache-ant-1.9.3

export PATH=$PATH:$ANT_HOME/bin

#findbugs

export FINDBUGS_HOME=/home/soft/findbugs-2.0.2

export PATH=$PATH:$FINDBUGS_HOME/bin
