Steve Loughran commented on MAPREDUCE-7254:
-------------------------------------------
looks like a config problem or a class "admin" is not on the classpath.
Not a hadoop problem; take it up with Sqoop through their user mailing list.
> sqoop on hadoop3.1 doesn't work

> I have a mysql table called admin with "linyouquan". And I want to import

> hadoop2.6 works, but sqoop on hadoop3.1 doesn't work.
> The following is my operation and error information of sqoop on hadoop3.1.
