For each item, i have 10 recommended items with a value of 1.0.
It sounds like a bug somewhere.

It's possible this is correct. 1.0 is the maximum similarity and
occurs when two vector are just a scalar multiple of each other (0
angle between them). It's possible there are several of these, and so
their 1.0 similarities dominate the result.

I saw something strange : all recommended items, returned by
mostSimilarItems(), have a value of 1.0.
Is it normal ?

This is probably because the Hadoop job does some sampling and pruning
