Subject Re: Sqoop Installation Problem
Date Wed, 21 Dec 2011 07:49:42 GMT
Hi,
I tried running sqoop without the environment variable. But unfortunately
it doesn't solve the problem. The classes cannot be found. So I am very
sure, that I need to set a classpath somewhere. But I don't know where.

I am working with version: Hadoop 0.20.203.0
