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 $

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

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 " " 13 --num-mappers 14 1
下列步骤和上述一致
