Apache Sqoop Hadoop和数据库数据迁移工具

Sqoop是一个用来将Hadoop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。

本文为大家讲解的是在linux下Sqoop的安装和配置教程，感兴趣的同学参考下．

Sqoop简介

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

环境说明

系统:linux

sqoop:sqoop 1.4.4

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<SQOOP_HOME>/conf/sqoop-env-template.sh 一份重命名为：<SQOOP_HOME>/conf/sqoop-env.sh

vi  <SQOOP_HOME>/conf/sqoop-env.sh

# 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 目录下。

测试数据准备

以MySQL 为例：

  • 192.168.6.77（hostname:Master.Hadoop）
  • database: test
  • 用户：root 密码：123456

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");

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
Found 4 items
-rw-r--r--   3 hadoop supergroup          0 2014-04-09 09:59 /user/hadoop/demo_blog/_SUCCESS
-rw-r--r--   3 hadoop supergroup         13 2014-04-09 09:59 /user/hadoop/demo_blog/part-m-00000
-rw-r--r--   3 hadoop supergroup         13 2014-04-09 09:59 /user/hadoop/demo_blog/part-m-00001
-rw-r--r--   3 hadoop supergroup         18 2014-04-09 09:59 /user/hadoop/demo_blog/part-m-00002

[hadoop@Master ~]$ hdfs dfs -cat /user/hadoop/demo_blog/part-m-0000*
1,micmiu.com
2,ctosun.com
3,baby.micmiu.com

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

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：

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：
