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

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： [INFO] Executing tasks

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] Or, try to reduce the Java heap size for the Javadoc goal using -Dminmemory=<size> and -Dmaxmemory=<size>.
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： main:

解决4：
