环境:  Hadoop2.7.2(NameNode HA,ResourceManage HA)

1.下载
[root@sht-sgmhadoopnn-01 hadoop]#  wget http://apache.mirrors.tds.net/sqoop/1.99.6/sqoop-1.99.6-bin-hadoop200.tar.gz
[root@sht-sgmhadoopnn-01 hadoop]#  tar -zxvf sqoop-1.99.6-bin-hadoop200.tar.gz
[root@sht-sgmhadoopnn-01 hadoop]# mv sqoop-1.99.6-bin-hadoop200 sqoop2


2.配置环境变量
[root@sht-sgmhadoopnn-01 ~]$ vim .bash_profile
添加如下内容: 
export SQOOP_HOME=/hadoop/sqoop2
export CATALINA_HOME=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs
export PATH=$SQOOP_HOME/bin:$PATH
保存退出即时生效: 
[root@sht-sgmhadoopnn-01 ~]source .bash_profile

 


3.配置服务端
[root@sht-sgmhadoopnn-01 hadoop]# cd server/conf
[root@sht-sgmhadoopnn-01 conf]# pwd
/hadoop/sqoop2/server/conf
[root@sht-sgmhadoopnn-01 conf]#

[root@sht-sgmhadoopnn-01 conf]$ vi catalina.properties
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/../lib/*.jar,/hadoop/hadoop/share/hadoop/common/*.jar,/hadoop/hadoop/share/hadoop/common/lib/*.jar,/hadoop/hadoop/share/hadoop/hdfs/*.jar,/hadoop/hadoop/share/hadoop/hdfs/lib/*.jar,/hadoop/hadoop/share/hadoop/mapreduce/*.jar,/hadoop/hadoop/share/hadoop/mapreduce/lib/*.jar,/hadoop/hadoop/share/hadoop/tools/lib/*.jar,/hadoop/hadoop/share/hadoop/tools/lib/*.jar,/hadoop/hadoop/share/hadoop/yarn/*.jar,/hadoop/hadoop/share/hadoop/yarn/lib/*.jar,/hadoop/hadoop/share/hadoop/httpfs/tomcat/lib/*.jar
###添加集群环境的本机的jar的目录

[root@sht-sgmhadoopnn-01 conf]$ vi sqoop.properties
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/hadoop/hadoop/etc/hadoop

 

4.添加mysql driver
[root@sht-sgmhadoopnn-01 conf]$ cd /hadoop/sqoop2/server/lib
[root@sht-sgmhadoopnn-01 lib]# rz
rz waiting to receive.

5.启动服务端
[root@sht-sgmhadoopnn-01 bin]# ./sqoop2-server start
Sqoop home directory: /hadoop/sqoop2
Setting SQOOP_HTTP_PORT:     12000
Setting SQOOP_ADMIN_PORT:     12001
Using   CATALINA_OPTS:      
Adding to CATALINA_OPTS:    -Dsqoop.http.port=12000 -Dsqoop.admin.port=12001
Using CATALINA_BASE:   /hadoop/sqoop2/server
Using CATALINA_HOME:   /hadoop/sqoop2/server
Using CATALINA_TMPDIR: /hadoop/sqoop2/server/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_67-cloudera
Using CLASSPATH:       /hadoop/sqoop2/server/bin/bootstrap.jar


6.启动客户端
[root@sht-sgmhadoopnn-01 bin]# sqoop2-shell
Sqoop home directory: /hadoop/sqoop2
Sqoop Shell: Type 'help' or '\h' for help.

#设置 连接服务端
sqoop:000> set server --host sht-sgmhadoopnn-01 --port 12000 --webapp sqoop

###创建mysql connector的link
sqoop:000> create link -c 4  #注意:这边的4是connector的id,表明创建的是一个generic jdbc connector
Creating link for connector with id 4
Please fill following values to create new link object
Name: mysql-link    #注意:Name是唯一的

Link configuration

JDBC Driver Class: com.mysql.jdbc.Driver
JDBC Connection String: jdbc:mysql://sht-sgmhadoopnn-01:3306/test1   #注意:jdbc:mysql://主机名(ip):端口/数据库名
Username: root
Password: **********
JDBC Connection Properties:
There are currently 0 values in the map:
entry#   #按回车键

There were warnings while create or update, but saved successfully.
Warning message: Can't connect to the database with given credentials: No suitable driver found for jdbc:jdbc://sht-sgmhadoopnn-01:/test1
New link was successfully created with validation status WARNING and persistent id 1
sqoop:000>


###创建hdfs connector的link
sqoop:000> create link -c 3 
Creating link for connector with id 3
Please fill following values to create new link object
Name: hdfs-link

Link configuration

HDFS URI: hdfs://mycluster/    #注意,为namenode HA的命名空间mycluster(当然也可以指定active namenode节点上,HDFS URI改为 hdfs://sht-sgmhadoopnn-01:8020/)
Hadoop conf directory: /hadoop/hadoop/etc/hadoop
New link was successfully created with validation status OK and persistent id 2
sqoop:000>


###查看 创建的link
sqoop:000> show link   
+----+------------+--------------+------------------------+---------+
| Id |    Name    | Connector Id |     Connector Name     | Enabled |
+----+------------+--------------+------------------------+---------+
| 1  | mysql-link | 4            | generic-jdbc-connector | true    |
| 2  | hdfs-link  | 3            | hdfs-connector         | true    |
+----+------------+--------------+------------------------+---------+
sqoop:000>
sqoop:000> show link -all

#####创建job对象,这个别写错了,使用LINK ID,而不是 Connector Id
#####使用这两个link Id来关联job的From和To部分。说的通俗一点,就是我们需要从哪里(From)读取数据,把这些数据导入(To)到哪里
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: testsqoop  #Name必须唯一

From database configuration

Schema name: test1   ##数据库的database name
Table name: person   ##该库的表
Table SQL statement:  #可选
Table column names:   #可选
Partition column name:  #可选
Null value allowed for the partition column:  #可选
Boundary query:       #可选
 
Incremental read

Check column:     #可选
Last value:       #可选

To HDFS configuration

Override null value:    #可选
Null value:             #可选
Output format:
  0 : TEXT_FILE
  1 : SEQUENCE_FILE
Choose:            #必选,为文本格式
Compression format:
  0 : NONE
  1 : DEFAULT
  2 : DEFLATE
  3 : GZIP
  4 : BZIP2
  5 : LZO
  6 : LZ4
  7 : SNAPPY
  8 : CUSTOM
Choose:         #必选 ,不压缩
Custom compression format:
Output directory: /sqoop/test  ###必选, hdfs的输出路径
Append mode:

Throttling resources

Extractors:  #可选,对应mapreduce的job中的map的数量
Loaders: 1      #可选,对应mapreduce的job中的reduce的数量
New job was successfully created with validation status OK  and persistent id 1
sqoop:000>

###查看job
qoop:000> show job
+----+-----------+----------------+--------------+---------+
| Id |   Name    | From Connector | To Connector | Enabled |
+----+-----------+----------------+--------------+---------+
| 1  | testsqoop | 4              | 3            | true    |
+----+-----------+----------------+--------------+---------+
sqoop:000>


###开启错误信息显示
sqoop:000> set option --name verbose --value true
Verbose option was changed to true
sqoop:000>

###开启job 1
sqoop:000> start job -j 1 -s
