Sqoop是一个用来将Hadoop（Hive、HBase）和关系型数据库中的数据相互转移的工具，可以将一个关系型数据库（例如：MySQL ,Oracle ,Postgres等）中的数据导入到Hadoop的HDFS中，也可以将HDFS的数据导入到关系型数据库中。Sqoop目前已经是Apache的顶级项目了，

Sqoop是一个用来将Hadoop（Hive、HBase）和关系型数据库中的数据相互转移的工具，可以将一个关系型数据库（例如：MySQL ,Oracle ,Postgres等）中的数据导入到Hadoop的HDFS中，也可以将HDFS的数据导入到关系型数据库中。 Sqoop目前已经是Apache的顶级项目了，目前版本是1.4.4 和 Sqoop2 1.99.3，本文以1.4.4的版本为例讲解基本的安装配置和简单应用的演示。
  • 安装配置
  • 准备测试数据
  • 导入数据到HDFS
  • 导入数据到Hive
  • 导入数据到HBase
[一]、安装配置 选择Sqoop 1.4.4 版本：sqoop-1.4.4.bin__hadoop-2.0.4-alpha.tar.gz 1.1、下载后解压配置： 
tar -zxvf sqoop-1.4.4.bin__hadoop-2.0.4-alpha.tar.gz /usr/local/
cd /usr/local
ln -s sqoop-1.4.4.bin__hadoop-2.0.4-alpha sqoop
1.2、环境变量配置 vi ~/.bash_profile ： 
#Sqoop  add by micmiu.com
export SQOOP_HOME=/usr/local/sqoop
export PATH=$SQOOP_HOME/bin:$PATH
1.3、配置Sqoop参数： 复制/conf/sqoop-env-template.sh 一份重命名为：/conf/sqoop-env.sh vi ?<sqoop_home>/conf/sqoop-env.sh</sqoop_home> 
# 指定各环境变量的实际配置
# Set Hadoop-specific environment variables here.
#Set path to where bin/hadoop is available
#export HADOOP_COMMON_HOME=
#Set path to where hadoop-*-core.jar is available
#export HADOOP_MAPRED_HOME=
#set the path to where bin/hbase is available
#export HBASE_HOME=
#Set the path to where bin/hive is available
#export HIVE_HOME=
ps：因为我当前用户的默认环境变量中已经配置了相关变量，故该配置文件无需再修改： 
# Hadoop  
export HADOOP_PREFIX="/usr/local/hadoop"  
export HADOOP_HOME=${HADOOP_PREFIX}  
export PATH=$PATH:$HADOOP_PREFIX/bin:$HADOOP_PREFIX/sbin
export HADOOP_COMMON_HOME=${HADOOP_PREFIX}  
export HADOOP_HDFS_HOME=${HADOOP_PREFIX}  
export HADOOP_MAPRED_HOME=${HADOOP_PREFIX}
export HADOOP_YARN_HOME=${HADOOP_PREFIX}  
# Native Path  
export HADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_PREFIX}/lib/native  
export HADOOP_OPTS="-Djava.library.path=$HADOOP_PREFIX/lib/native" 
# Hadoop end
#Hive
export HIVE_HOME=/usr/local/hive
export PATH=$HIVE_HOME/bin:$PATH
#HBase
export HBASE_HOME=/usr/local/hbase
export PATH=$HBASE
#add by micmiu.com
1.4、驱动jar包 下面测试演示以MySQL为例，则需要把mysql对应的驱动lib文件copy到 <sqoop_home>/lib</sqoop_home> 目录下。 [二]、测试数据准备 以MySQL 为例：
  • 192.168.6.77（hostname:Master.Hadoop）
  • database: test
  • 用户：root 密码：micmiu
准备两张测试表一个有主键表demo_blog，一个无主键表 demo_log： 
CREATE TABLE `demo_blog` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `blog` varchar(100) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;
CREATE TABLE `demo_log` (
  `operator` varchar(16) NOT NULL,
  `log` varchar(100) NOT NULL
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;
插入测试数据： 
insert into demo_blog (id, blog) values (1, "micmiu.com");
insert into demo_blog (id, blog) values (2, "ctosun.com");
insert into demo_blog (id, blog) values (3, "baby.micmiu.com");
insert into demo_log (operator, log) values ("micmiu", "create");
insert into demo_log (operator, log) values ("micmiu", "update");
insert into demo_log (operator, log) values ("michael", "edit");
insert into demo_log (operator, log) values ("michael", "delete");
[三]、导入数据到HDFS 3.1、导入有主键的表 比如我需要把表 demo_blog (含主键) 的数据导入到HDFS中，执行如下命令： 
sqoop import --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_blog
执行过程如下： 
$ sqoop import --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_blog

验证导入到hdfs上的数据： 
$ hdfs dfs -ls /user/hadoop/demo_blog

ps：默认设置下导入到hdfs上的路径是：?/user/username/tablename/(files)，比如我的当前用户是hadoop，那么实际路径即：?/user/hadoop/demo_blog/(files)。 如果要自定义路径需要增加参数：--warehouse-dir 比如： 
sqoop import --connect jdbc:mysql://Master.Hadoop/test --username root --password micmiu --table demo_blog --warehouse-dir /user/micmiu/sqoop
3.2、导入不含主键的表 比如需要把表 demo_log（无主键） 的数据导入到hdfs中，执行如下命令： 
sqoop import --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_log --warehouse-dir /user/micmiu/sqoop --split-by operator
ps：无主键表的导入需要增加参数? --split-by xxx ?或者 -m 1 执行过程： 
$ sqoop import --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_log --warehouse-dir /user/micmiu/sqoop --split-by operator

[四]、导入数据到Hive 比如把表demo_blog 数据导入到Hive中，增加参数 --hive-import?： 
sqoop import --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_blog  --warehouse-dir /user/sqoop --hive-import --create-hive-table
执行过程如下： 
$ sqoop import --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_blog  --warehouse-dir /user/sqoop --hive-import --create-hive-table

[五]、导入数据到HBase 演示把表 demo_blog 数据导入到HBase ，指定Hbase中表名为 demo_sqoop2hbase 的命令： 
sqoop  import  --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_blog --hbase-table demo_sqoop2hbase --hbase-create-table --hbase-row-key id --column-family url
执行过程： 
$ sqoop  import  --connect jdbc:mysql://192.168.6.77/test --username root --password micmiu --table demo_blog --hbase-table demo_sqoop2hbase --hbase-create-table --hbase-row-key id --column-family url
