>
> While loading a large number of pre-trained vectors into Spark MLLIB's
> Word2Vec model, will result in java.lang.NegativeArraySizeException.
> Code -
> https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/feature/Word2Vec.scala#L597
> Test with number of vectors greater than 16777215 with size of each vector
> 128 or more.
> there is Integer Overflow happening here. Should be an easy fix.
