Oozie执行Sqoop，传入参数（注意，在使用--query时，参数中一定不要带有空格，否则出错）
1. 新建一个workflow
2. 拖入一个sqoop
3. sqoop抽取命令如下（建议先在命令行试下，因为oozie的错误提示很委婉，基本看不出错误原因）
sqoop import --connect jdbc:mysql://localhost:3306/spider_new --username root --password 1234qwer --target-dir /user/fengz/brand/spider_data/amac/amac_fund_${date} --delete-target-dir --fields-terminated-by '`' --query select * from amac_fund where update_time between '${start_time}' and '${end_time}' and \$CONDITIONS -m 1
这是在命令行可执行的命令，其中有三个动态参数，${date}、${start_time}、${end_time}，此处做了一个import的导入操作，把指定数据抽取到HDFS路径下，用了--query写SQL语句抽取想要的数据，此处需要注意，如果使用--query，必须要带\$CONDITIONS，否则执行失败。
4. 填入oozie-sqoop中，需要填入的内容如下
import --connect jdbc:mysql://localhost:3306/spider_new --username root --password 1234qwer --target-dir /user/fengz/brand/spider_data/amac/amac_fund_${date} --delete-target-dir --fields-terminated-by ` --query select * from amac_fund where update_time between '${start_time}' and '${end_time}' and \$CONDITIONS -m 1
注意：指定分隔符时，要把单引号去掉，下边还有一个大坑
5. 添加参数
6. 启动，填入参数
7. 那么问题来了，报错是必须的
oozie在解析sqoop语句的时候，是根据空格来分割的，那就恶心了，日期字段中间带有空格，就像这样

再看下oozie的错误提示，呵呵呵....发现一点鸟用都没有

以后用的时候注意下就好了。那这个问题怎么解决？用shell，shell脚本里边写sqoop抽取。
