Re: can't compile the mapreduce project in eclipse
Did you add all dependencies of the source code?

And here, sqoop is missing. I don't why this library is required for
this, but, it seems to be the problem.
You should add all the required dependencies on your CLASSPATH variables
on Windows->Preferences->Java->Build Path->Classpath Variables

Please, go to the Cloudera Resources Site and you can search the
Eclipse/Hadoop screencast that explains these details easy and quickly
how to build the hadoop project.
