sqoop部署

- 下载

在hadoop家目录下创建一个app目录

[hadoop@hadoop001 ~]$ mkdir app

[hadoop@hadoop001 app]$ pwd
/home/hadoop/app

[hadoop@hadoop001 app]$ wget http://archive.cloudera.com/cdh5/cdh/5/sqoop-1.4.6-cdh5.7.0.tar.gz  --下载sqoop安装包  我们用的是cdh环境，所以下载的也是cdh安装包

- 解压
[hadoop@hadoop001 app]$ tar -zxvf sqoop-1.4.6-cdh5.7.0.tar.gz

[hadoop@hadoop001 app]$ ll
drwxr-xr-x 10 hadoop hadoop 4096 Apr 4 15:10 sqoop-1.4.6-cdh5.7.0
-rw-r--r-- 1 root root 29966286 Apr 3 17:38 sqoop-1.4.6-cdh5.7.0.tar.gz

-配置环境变量

[hadoop@hadoop001 ~]$ vi ~/.bash_profile

export SQOOP_HOME=/home/hadoop/app/sqoop

export PATH=$SQOOP_HOME/bin:$PATH

[hadoop@hadoop001 ~]$ source ~/.bash_profile   

-进入conf目录

[hadoop@hadoop001 ~]$ cd $SQOOP_HOME/conf    

-复制配置文件模板并改名

[hadoop@hadoop001 conf]$ cp sqoop-env-template.sh sqoop-env.sh

-编辑环境信息

[hadoop@hadoop001 conf]$ vi sqoop-env.sh

-解开hadoop和hive的注释，并配置正确的目录

#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/home/hadoop/app/hadoop-2.6.0-cdh5.7.0

#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/home/hadoop/app/hadoop-2.6.0-cdh5.7.0

#set the path to where bin/hbase is available
#export HBASE_HOME=

#Set the path to where bin/hive is available
export HIVE_HOME=/home/hadoop/app/hive-1.1.0-cdh5.7.0

导入jdbc驱动jar包

[hadoop@hadoop001 conf]$ cd $SQOOP_HOME/lib

[hadoop@hadoop001 lib]$ wget http://central.maven.org/maven2/mysql/mysql-connector-java/5.1.27/mysql-connector-java-5.1.27.jar

导入json包

[hadoop@hadoop001 lib]$ wget http://www.java2s.com/Code/JarDownload/java-json/java-json.jar.zip

[hadoop@hadoop001 lib]$ unzip java-json.jar.zip

导入hive-exec-**.jar

[hadoop@hadoop001 lib]$ cp $HIVE_HOME/lib/hive-exec-**.jar $SQOOP_HOME/lib

输入sqoop version检查是否安装成功

[hadoop@hadoop001 lib]$ sqoop version
