查看如何编译安装

mvn clean package -Pdist,native,docs -DskipTests -Dtar
编译过程中，需要下载很多包，等待时间比较长。当看到hadoop各个项目都编译成功,即出现一系列的SUCCESS之后，即为编译成功。

有些包下载卡住，重复执行上面的命令，或可以根据提示到相应的网址(https://repo.maven.apache.org/maven2)下载放到指定位置

出现错误1：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (site) on project hadoop-common: An Ant BuildException has occured: input file /home/hadoop/hadoop-2.6.4-src/hadoop-common-project/hadoop-common/target/findbugsXml.xml does not exist [ERROR] around Ant part ...... @ 44:256 in /home/hadoop/hadoop-2.6.4-src/hadoop-common-project/hadoop-common/target/antrun/build-main.xml
解决办法1：
参考：http://www.itnose.net/detail/6143808.html
从该命令删除docs参数再运行mvn package -Pdist,native -DskipTests -Dtar

出现错误2：

解决2：
卡在这里，应该是不能下载
下载上传到指定位置

出现错误3：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8.1:jar (module-javadocs) on project hadoop-hdfs: MavenReportException: Error while creating archive: [ERROR] ExcludePrivateAnnotationsStandardDoclet [ERROR] Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000f31a4000, 130400256, 0) failed; error='Cannot allocate memory' (errno=12) [ERROR] # [ERROR] # There is insufficient memory for the Java Runtime Environment to continue.

[ERROR] Or, try to reduce the Java heap size for the Javadoc goal using -Dminmemory= and -Dmaxmemory=.
解决3：
应该是内存不够，没有分配swap
添加2G swap分区
添加或扩大交换分区
dd if=/dev/zero of=/home/swap bs=512 count=4096000
bs 是扇区大小 bs=512 指大小为512B count为扇区数量
表示创建一个大小为4G 的文件 /home/swap 用空值填充。of位置可以自己调整。

查看当前分区的大小
free -m

格式化并挂载
mkswap /home/swap
swapon /home/swap

查看挂载情况
swapon -s

开机自动挂载
vim /etc/fstab
/home/swap swap swap defaults 0 0

想写在分区
swapoff /home/swap

出现问题4：

解决4：
网络问题，同上

在hadoop-dist/target/已经生成了可执行文件

拷贝到用户目录
cp -r hadoop-2.6.4 ~/

配置

两台机免密互通

ssh-keygen
各自生成的公钥放到另一台机上
cat id_rsa_else.pub >> authorized_keys chmod 600 authorized_keys

网络规划：

hadoop1 123.206.33.182 slave hadoop0 114.215.92.77 master

配置hosts

vim /etc/hosts 123.206.33.182 hadoop1 tx lizer_tx 114.215.92.77 hadoop0 ali lizer_ali

配置环境变量

vim /etc/profile export HADOOP_HOME=/home/hadoop/hadoop-2.6.4 export PATH=$HADOOP_HOME/bin:$PATH

Hadoop配置

配置文件放在$HADOOP_HOME/etc/hadoop/下
修改一下配置：

vim hadoop-env.sh
