环境准备
OS: CentOS 6.4 x86_64
Servers:
hadoop-master: 172.17.20.230 内存10G
- namenode
- hbase-master

hadoop-secondary: 172.17.20.234 内存10G
- secondarybackupnamenode,jobtracker
- hive-server,hive-metastore
- oozie

hadoop-node-1: 172.17.20.231 内存10G sudo yum install hbase-regionserver
- datanode,tasktracker
- hbase-regionserver,zookeeper-server

hadoop-node-2: 172.17.20.232 内存10G
- datanode,tasktracker
- hbase-regionserver,zookeeper-server

hadoop-node-3: 172.17.20.233 内存10G
- datanode,tasktracker
- hbase-regionserver,zookeeper-server

对以上角色做一些简单的介绍：
namenode - 整个HDFS的命名空间管理服务
secondarynamenode - 可以看做是namenode的冗余服务
jobtracker - 并行计算的job管理服务
datanode - HDFS的节点服务
tasktracker - 并行计算的job执行服务
hbase-master - Hbase的管理服务
hbase-regionServer - 对Client端插入，删除，查询数据等提供服务
zookeeper-server - Zookeeper协作与配置管理服务
hive-server - Hive的管理服务
hive-metastore - Hive的元存储，用于对元数据进行类型检查与语法分析
oozie - Oozie是一种Java Web应用程序，用于工作流的定义和管理

本文定义的规范，避免在配置多台服务器上产生理解上的混乱：
以下操作都只需要在 Oozie 所在主机，即 hadoop-secondary 上执行。

1. 安装前的准备
Hadoop集群(CDH4)实践之 (3) Hive搭建

2. 安装Oozie
$ sudo yum install oozie oozie-client

3. 创建Oozie数据库
$ mysql -uroot -phiveserver

 
mysql> create database oozie;
mysql> grant all privileges on oozie.* to 'oozie'@'localhost' identified by 'oozie';
mysql> grant all privileges on oozie.* to 'oozie'@'%' identified by 'oozie';
mysql> exit;

4.配置oozie-site.xml
$ sudo vim /etc/oozie/conf/oozie-site.xml

5. 配置Oozie Web Console
$ cd /tmp/
$ wget http://archive.cloudera.com/gplextras/misc/ext-2.2.zip
$ cd /var/lib/oozie/
$ sudo unzip /tmp/ext-2.2.zip
$ cd ext-2.2/
$ sudo -u hdfs hadoop fs -mkdir /user/oozie
$ sudo -u hdfs hadoop fs -chown oozie:oozie /user/oozie

6. 配置Oozie ShareLib
$ mkdir /tmp/ooziesharelib
$ cd /tmp/ooziesharelib
$ tar xzf /usr/lib/oozie/oozie-sharelib.tar.gz
$ sudo -u oozie hadoop fs -put share /user/oozie/share
$ sudo -u oozie hadoop fs -ls /user/oozie/share
$ sudo -u oozie hadoop fs -ls /user/oozie/share/lib
$ sudo -u oozie hadoop fs -put /usr/lib/hive/lib/hbase.jar /user/oozie/share/lib/hive/
$ sudo -u oozie hadoop fs -put /usr/lib/hive/lib/zookeeper.jar /user/oozie/share/lib/hive/
$ sudo -u oozie hadoop fs -put /usr/lib/hive/lib/hive-hbase-handler-0.10.0-cdh4.5.0.jar /user/oozie/share/lib/hive/
$ sudo -u oozie hadoop fs -put /usr/lib/hive/lib/guava-11.0.2.jar /user/oozie/share/lib/hive/

7. 启动Oozie
$ sudo service oozie start

8. 访问Oozie Web Console

http://hadoop-secondary:11000/oozie

9. 至此，Oozie的搭建就已经完成。
