sqoop1.99.4的安装和使用

一.环境介绍：sqoop版本:1.99.4-hadoop200 hadoop版本:hadoop2.2.0安装路径是/usr/local/sqoop

二.sqoop1.99.4安装1.解压安装文件到/usr/

一.环境介绍：

sqoop版本:1.99.4-hadoop200

hadoop版本:hadoop2.2.0

安装路径是/usr/local/sqoop

二.sqoop1.99.4安装

1.解压安装文件到/usr/local/sqoop目录
2.修改环境变量 sudo vi /etc/profile

export SQOOP_HOME=/usr/local/sqoop  
export PATH=$SQOOP_HOME/bin:$PATH  
export CATALINA_HOME=$SQOOP_HOME/server  
export LOGDIR=$SQOOP_HOME/logs

使立即生效：source /etc/profile

3.修改sqoop配置文件
(1)修改/usr/local/sqoop/server/conf/sqoop.properties
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/usr/local/hadoop2.2.0/etc/hadoop #hadoop的安装目录中的配置目录
(2)修改/usr/local/sqoop/server/conf/catalina.properties
common.loader=/usr/local/sqoop/hadoop_lib     #需要用到的Jar包目录(也可以直接引用多个目录，用‘，

4.成立Jar包目录
(1)在sqoop根目录下新建文件夹hadoop_lib
(2)把hadoop相关依赖jar包拷贝到该目录
/usr/local/hadoop2.2.0/share/hadoop/common/*.jar
/usr/local/hadoop2.2.0/share/hadoop/common/lib/*.jar
/usr/local/hadoop2.2.0/share/hadoop/hdfs/*.jar
/usr/local/hadoop2.2.0/share/hadoop/hdfs/lib/*.jar
/usr/local/hadoop2.2.0/share/hadoop/mapreduce/*.jar
/usr/local/hadoop2.2.0/share/hadoop/mapreduce/lib/*.jar
/usr/local/hadoop2.2.0/share/hadoop/tools/*.jar
/usr/local/hadoop2.2.0/share/hadoop/tools/lib/*.jar
/usr/local/hadoop2.2.0/share/hadoop/yarn/*.jar
/usr/local/hadoop2.2.0/share/hadoop/yarn/lib/*.jar
/usr/local/hadoop2.2.0/share/hadoop/httpfs/tomcat/lib/*.jar 
(3)把/usr/local/sqoop/server/bin/*.jar和/usr/local/sqoop/server/lib/*.jar拷贝到该目录

5.赋予权限
sqoop.sh默认是没有运行权限的，所以需要给sqoop.sh赋予运行权限
sudo chmod 777 /usr/local/sqoop/bin/sqoop.sh
运行sqoop.sh,此时会提示另外一个脚本没有运行,可根据提示赋予权限给相应文件
如果嫌麻烦，可以用一个一劳永逸的方法，就是把整个sqoop目录赋予所有权限。
sudo chmod 777 -R /usr/loacl/sqoop

6.工具验证
cd /usr/local/sqoop/bin
./sqoop2-tool verify

7.启动sqoop server
cd /usr/local/sqoop/bin
./sqoop2-server start

8.查看日志文件，如果日志文件没有报错，说明sqoop启动成功，否则启动失败
cat /usr/local/sqoop/server/logs/catalina.out

9.进入客户端shell
cd /usr/local/sqoop/bin
./sqoop2-shell

三.sqoop1.99.4的使用
1.配置客户端使用服务：set server --host 127.0.0.1 --port 12000 --webapp sqoop

2.建立连接
(1)建立JDBC连接
create link --cid 1 #我的是1，可以通过show connector查看
Please fill following values to create new link object
Name: First Link

Link configuration
JDBC Driver Class: com.mysql.jdbc.Driver
JDBC Connection String: jdbc:mysql://localhost:3306/database
Username: sqoop
Password: *****
JDBC Connection Properties:
There are currently 0 values in the map:
entry#protocol=tcp
New link was successfully created with validation status OK and persistent id 1

(2)建立HDFS连接
create link --cid 2
Creating link for connector with id 1 
Please fill following values to create new link object 
Name: Second Link

Link configuration HDFS URI: hdfs://nameservice1:8020/ 
New link was successfully created with validation status OK and persistent id 2

3.创建任务
sqoop:000> create job -f 1 -t 2
 Creating job for links with from id 1 and to id 2
 Please fill following values to create new job object
 Name: Sqoopy
