storing MatrixFactorizationModel (pyspark)

[Antony Mayi]

Hi,
when getting the model out of ALS.train it would be beneficial to store it (to 
disk) so the model can be reused later for any following predictions. I am 
using pyspark and I had no luck pickling it either using standard pickle module 
or even dill.
does anyone have a solution for this (note it is pyspark)?
thank you,Antony.
