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
- sqoop

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
sqoop - Sqoop是一个转换工具,用于在关系型数据库与HDFS之间进行数据转换

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 Sqoop 所在主机,即 hadoop-secondary 上执行。

1. 安装前的准备
Hadoop集群(CHD4)实践之 (4) Oozie搭建

2. 安装Sqoop
$ sudo yum install sqoop sqoop-metastore

3. 启动Sqoop Metastore
$ sudo service sqoop-metastore start

4. 配置JDBC驱动
MySQL JDBC Driver:
$ sudo yum install mysql-connector-java
$ sudo ln -s /usr/share/java/mysql-connector-java.jar /usr/lib/sqoop/lib/mysql-connector-java.jar

Microsoft SQL Server JDBC Driver:
$ wget http://download.microsoft.com/download/0/2/A/02AAE597-3865-456C-AE7F-613F99F850A8/sqljdbc_4.0.2206.100_enu.tar.gz
$ tar xzvf sqljdbc_4.0.2206.100_enu.tar.gz
$ sudo cp sqljdbc_4.0/enu/sqljdbc4.jar /usr/lib/sqoop/lib/

5. 配置HCAT_HOME
$ sudo vim /etc/profile.d/sqoop.sh

 
export HCAT_HOME=/var/lib/sqoop
Copy after login

$ source /etc/profile

6. 至此,Sqoop的安装就已经完成。
