Subject Re: 0.21 found interface but class was expected
Date Fri, 12 Nov 2010 16:04:39 GMT
Hi Steve,
we had a similar problem. We've compiled our code with version 0.21  
but included the wrong jars into the classpath. (version 0.20.2;  
NInputFormat.java). It seems that Hadoop changed this class to an  
interface, maybe you've a simliar problem.
Hope this helps.
Sebastian
