Sqoop详细介绍包括：sqoop命令，原理，流程

文章里面的下面这条语句
sqoop list-databases -connect jdbc:mysql://localhost:3306/ -username root -password xhq123
其中 -connect、-username、-password 里的连字符竟然是中文的，结果报以下错误：

[hadoop@mdhadoop ~]$ sqoop list-tables –connect jdbc:mysql://localhost/test –username root –password root
15/06/11 11:15:23 INFO sqoop.Sqoop: Running Sqoop version: 1.4.4-cdh5.0.0

改成英文连字符就好了
