这条命令不用跟驱动的类名是因为sqoop默认支持mysql的，如果要跟jdbc驱动的类名用
# sqoop list-tables --connect jdbc:mysql://localhost/sqoop_test --username root --password root --driver com.mysql.jdbc.Driver
导入数据到hdfs
sqoop import --connect jdbc:mysql://localhost:3306/sqoop_test --username root --password root --table employee --m 1 --target-dir /user/test3
