Are you sure you have actually increased the RAM (how exactly did you do that
and does it show in Spark UI)
Also use the SPARK UI an

waiting for free core (Thread contexts also occupy additional RAM )

This is most likely due to the internal implementation of ALS in MLib. Probably
for each parallel unit of execution (partition in Spark terms) the
implementation allocates and uses a RAM buffer where it keeps interim results
during the ALS iterations
If we assume that the size of that intern
