Fwd: Master example.MovielensALS

Hi,

I just built the master today and I was testing the IR metrics (MAP and
prec@k) on Movielens data to establish a baseline...

I am getting a weird error which I have not seen before:

MASTER=spark://TUSCA09LMLVT00C.local:7077 ./bin/run-example
mllib.MovieLensALS --kryo --lambda 0.065
hdfs://localhost:8020/sandbox/movielens/

org.apache.spark.examples.mllib.MovieLensALS$Params; no valid constructor

For Params there is no valid constructor....Is this due to the
AbstractParam change ?

Thanks.
