19 nameNode=hdfs://hadoop:8020
20 jobTracker=hadoop:8032
21 queueName=default
22 oozieAppsRoot=user/root/oozie-apps
23 oozieDataRoot=user/root/oozie/datas
24 
25 oozie.use.system.libpath=true
26 
27 oozie.wf.application.path=${nameNode}/${oozieAppsRoot}/sqoop-import-user
28 
29 outputDir=sqoop-import-user/output

4.编辑workflow.xml   

      注意 在这里如果要指定sqoop导出数据的格式  要用双引号 单引号没效果的 

      而且只识别单字符 不识别多字符 这里的$$$ 导出的数据格式 是 $

43     </kill>
44     <end name="end"/>
45 </workflow-app>

5：上传到hdfs

1 bin/hdfs dfs -put /opt/cdh-5.3.6/oozie-4.0.0-cdh5.3.6/oozie-apps/sqoop-import-user /user/root/oozie-apps

 

6：启动测试

1  bin/oozied.sh start
2 
3  export OOZIE_URL=http://localhost:11000/oozie
4  
5  bin/oozie job -config oozie-apps/sqoop-import-user/job.properties -run

 

 

 

 

 

方式二 ： 简化版

配置workflow.xml

 1 <?xml version="1.0" encoding="UTF-8"?>

31                     <name>mapred.job.queue.name</name>
32                     <value>${queueName}</value>
33                 </property>
34             </configuration>
35             <command>import --options-file imp-user.sql</command>
36         </sqoop>
37         <ok to="end"/>
38         <error to="fail"/>
39     </action>
40 
41     <kill name="fail">
42         <message>Sqoop failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
43     </kill>
44     <end name="end"/>
45 </workflow-app>

编辑sql脚本

 1 --connect
 2 jdbc:mysql://172.16.71.27:3306/babasport
 3 --username
 4 root
 5 --password
 6 root
 7 --table
 8 bbs_buyer
 9 --target-dir
10 /user/root/oozie/datas/sqoop-import-user/output
11 --fields-terminated-by
12 "\t"
13 --num-mappers
14 1

下列步骤和上述一致
