I think your other post has similar issue. I think there are two things missing here:
1. Java connector needs to be installed, not just moved to sqoop/lib. If you can’t install the connector you need to copy .jar file that we can send you if needed.
2. The error message seems to complain about Java version. “… It seems as though you are running sqoop with a JRE.”
Can you please try following command?
C:\Java\jdk1.7.0_51>set | findstr JAVA
You should see JDK location.
Hope this helps,
