Minor Description
mllib.feature.Word2Vec at line 442: https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/feature/Word2Vec.scala#L442 uses `.head` to get the vector size. But it would throw an empty iterator error if the `minCount` is large enough to remove all words in the dataset.
But due to this is not a common scenario, so maybe we can ignore it. If so, we can close the issue directly. If not, I can add some code to print more elegant error hits.
