Hadoop-2.2编译

由于Hadoop-2.2只发布了32位的版本,所以如果是在64位操作系统上,需要重新编译

安装 maven

安装maven,查找其安装目录

sudo apt-get intall maven
Find /usr -name “*maven*” 

根据其安装目录添加环境变量

export M2_HOME=/usr/shared/maven
export PATH=$PATH:$M2_HOME/bin 
export MAVEN_OPTS="-Xms256m -Xmx512m"

安装 google protobuf

wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz

/configure--prefix=/usr/local/protobuf   
sudo make && sudo make install
sudo vim /etc/ld.so.conf   [添加/usr/local/lib]
ldconfig

安装Cmake

sudo apt-get install cmake

安装依赖库

libglib2.0-dev libssl-dev

pom.xml 中有个bug,添加下面patch即可

参考 https://issues.apache.org/jira/browse/HADOOP-10110

开始编译:

mvn package -Pdist,native -DskipTests -Dtar 

 

常见错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (make) on project hadoop-hdfs: An Ant BuildException has occured: exec returned: 1 -> [Help 1]

安装libglib2.0-dev

 

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (make) on project hadoop-pipes: An Ant BuildException has occured: exec returned: 1 -> [Help 1]

安装libssl-dev

参考 https://issues.apache.org/jira/browse/HADOOP-10110

 

最后在目录~/hadoop-2.2.0-src/hadoop-dist/target中有一个hadoop-2.2.0的目录就是编译出来的版本

 

Hadoop-2.2环境配置

添加用户

每个节点都添加yarn用户

 

添加用户

sudo adduser yarn

 

把用户添加到hadoop组中(如果你没有一个hadoop的组,需要新建这个组)

sudo gpasswd -a yarn hadoop

 

给yarn用户添加sudo权限

sudo vim /etc/sudoers

 

添加如下语句

yarn ALL=(ALL:ALL) ALL

 

ssh配置

针对master

sudo apt-get install openssh-server

ssh-keygen(一直按enter即可)

在~/.ssh目录下,有一个id_rsa(私钥),一个id_rsa.pub(公钥)

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

输入ssh localhost确认是否需要输入密码

 

拷贝authorized_keys 到slave1~slave3节点

 

scp authorized_keys yarn@slave1:~/.ssh/

scp authorized_keys yarn@slave2:~/.ssh/

scp authorized_keys yarn@slave3:~/.ssh/

 

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/

针对salves

都要执行ssh-keygen

最后在master节点上使用ssh slave1等测试

 

其他

每个节点上面都需要添加如下ip

vim /etc/hosts

219.219.216.48 master

219.219.216.47 slave1

219.219.216.45 slave2

219.219.216.46 slave3

参考

http://dongxicheng.org/mapreduce-nextgen/hadoop-yarn-install/

 

配置文件

hadoop-env.sh

添加JAVA_HOME环境变量

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/

Core-site.xml

 

<configuration>
        <property>
                <name>fs.defaultFS</name>
                <value>hdfs://master:8020</value>
                <final>true</final>
        </property>
        <property>
                <name>dfs.replication</name>
                <value>2</value>

        <property>
                <name>hadoop.tmp.dir</name>
                <value>/home/yarn/hadoop-files/tmp</value>
        </property>
</configuration>

Hdfs-site.xml

<configuration>
        <property>
        <name>dfs.namenode.name.dir</name>
                <value>/home/yarn/hadoop-files/name</value>
        </property>
        <property>
                <name>dfs.datanode.data.dir</name>

        </property>
        <property>
                <name>dfs.replication</name>
                <value>2</value>
        </property>
        <property>
                <name>hadoop.tmp.dir</name>
                <value>/home/yarn/hadoop-files/tmp/</value>
                <description>A base for other temporary directories.</description>
        </property>
</configuration>

红色部分根据你实际的目录而定。

 

mapred-site.xml

<configuration>
        <property>
                <name>mapreduce.framework.name</name>
                <value>yarn</value>
        </property>
        <property>
                <name>mapred.child.java.opts</name>
                <value>-Xmx1024m</value>
        </property>
</configuration>

yarn-site.xml

<configuration>
   <property>
     <name>yarn.nodemanager.aux-services</name>
     <value>mapreduce_shuffle</value>
  </property>
  <property>
     <name>yarn.resourcemanager.address</name>
     <value>master:8032</value>
  </property>
  <property>
      <name>yarn.resourcemanager.resource-tracker.address</name>
      <value>master:8031</value>

  <property>
      <name>yarn.resourcemanager.admin.address</name>
      <value>master:8033</value>
  </property>
  <property>
      <name>yarn.resourcemanager.scheduler.address</name>
      <value>master:8030</value>
  </property>

  <property>
      <name>yarn.web-proxy.address</name>
      <value>master:8888</value>
  </property>
  <property>
     <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
     <value>org.apache.hadoop.mapred.ShuffleHandler</value>
  </property>
  <property>
     <name>yarn.nodemanager.loacl-dirs</name>
     <value>/home/yarn/hadoop-2.2.0/hadoop-files/hadoop-loacl-dirs/</value>
     <final>true</final>
  </property>
</configuration>

 

 

其他可能需要设置的环境变量

export M2_HOME=/usr/share/maven
export PATH=$PATH:$M2_HOME/bin:~/hadoop-2.2.0/bin
export MAVEN_OPTS="-Xms2048m -Xmx2048m"
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/
export HADOOP_HOME="/home/yarn/hadoop-2.2.0"
export HADOOP_PREFIX="/home/yarn/hadoop-2.2.0"
export YARN_HOME=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop/
export YARN_CONF_DIR=$HADOOP_CONF_DIR
export PATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH
export SCALA_HOME=/usr/share/scala/
export PATH=$SCALA_HOME/bin/:$PATH

 

测试

改变文件用户组属性

./hdfs dfs -chgrp -R yarn
./hdfs dfs -mkdir /yarn

这样yarn文件夹就属于用户yarn的了
