It seems that the output of MLlib's *StandardScaler*(*withMean=*True,
*withStd*=True)are not as expected.
The above configuration is expected to do the following transformation:
X -> Y = (X-Mean)/Std - Eq.1

overflow). In general if a question is well suited for stackoverflow its
probably better suited to the user@ list instead of the dev@ list so I've
cc'd the user@ list for you.
As far as handling empty partitions wh
Actually I think it is possibly that an user/developer needs the
standardized features with population mean and std in some cases. It would
be better if StandardScaler can offer the option to do that.
