spark-0.8.1安装——hadoop-2.2.0 x64

Hadoop-2.2.0 x64编译

1. hadoop源码hadoop-2.2.0-src.tar.gz下载并解压

2. 安装必要工具：yum install maven ncurses-devel openssl-devel cmake

3. 编译：

  3.1 cd hadoop-2.2.0-src

  3.2 mvn package -Pdist,native -DskipTests -Dtar

生成的发布包为hadoop-dist/target/hadoop-2.2.0.tar.gz

hadoop-2.2.0 集群配置

1. 解压前面编译的发布包hadoop-2.2.0.tar.gz，以下操作均在master机器Fedora01上操作

  tar -zxvf hadoop-2.2.0.tar.gz -C /usr/local

  ln -snf hadoop-2.2.0 hadoop2

  cd hadoop2/etc/hadoop

2. 配置以下几个文件，参考http://blog.csdn.net/licongcong_0224/article/details/12972889

Fedora01
Fedora02
Fedora03
Fedora04

3. 环境变量配置，同步到其他机器

  3.1 增加下面两行到~/.bashrc，并source ~/.bashrc

export HADOOP_HOME="/usr/local/hadoop2"
export PATH="$HADOOP_HOME/bin:$PATH"
  3.2 同步

cd /usr/local

~/sync-cluster.sh hadoop2 hadoop-2.2.0 ~/.bashrc

4. 启动集群

cd /usr/local/hadoop2

./bin/hdfs namenode -format

./sbin/start-dfs.sh

jps #Fedora01上应该看到4个进程DataNode  NameNode  Jps  SecondaryNameNode  其他机器应该看到2个进程DataNode  Jps

./sbin/start-yarn.sh

jps #Fedora01上应该看到6个进程DataNode  NameNode  Jps  SecondaryNameNode  ResourceManager  NodeManager 其他机器应该看到3个进程DataNode  Jps NodeManager

5. 配置selinux和firewalld

  5.1 setenfore 0

  5.2 编辑/etc/selinux/conf文件，设置SELINUX=disabled

  5.3 systemctl stop firewalld.service; systemctl disable firewalld.service 这里很坑人的是iptables在Fedora20里已经不用了，默认就是禁止了的，而改用了firewalld。

5. 测试，无错误

[root@Fedora01 ~]# cd

[root@Fedora01 ~]# hadoop fs -mkdir -p /data/test
[root@Fedora01 ~]# hadoop fs -put sync-cluster.sh /data/test
[root@Fedora01 ~]# hadoop fs -ls /data/test
Found 1 items

-rw-r--r--   3 root supergroup        763 2014-02-07 21:42 /data/test/sync-cluster.sh

监控页面，这里为了方便在主机Fedora上的/etc/hosts文件配置了Fedora01与IP的对应关系，如果没配置，把Fedora01改为对应的IP即可
