I can't run the code in 《Mahout In Action》 under Mahout 0.7,what's happening ?

I'm reading the book 《Mahout In Action》 and i'd like to try the code myself.

But i found lots of the code can't run(Most of the issues are method can't be found).

1、RandomSeedGenerator.chooseRandomPoints(pointVectors, k); chooseRandomPoints can't be found.

2、new Cluster(v, clusterId++, measure); the constructor can't be found.

there are many of these kind of issues.

Can anyone tell me how to find those methods ?
