If the missing values are 0, then you can also look into implicit formulation...

We don't handle missing value imputation in the current version of
MLlib. In future releases, we can store feature information in the
dataset metadata, which may store the default value to replace missing
values. But no one is committed to work on this feature. For now, you
can filter out examples containing missing values and use the rest for
training. -Xiangrui
