> Project: Spark
> Issue Type: Test
> Components: MLlib
> Reporter: Feynman Liang
> Assignee: Meihua Wu
> Priority: Minor
> Labels: starter
>
> We need to add a unit test to {{LDASuite}} which check that empty documents
> are handled appropriately without crashing. This would require defining an
> empty corpus within {{LDASuite}} and adding tests for the available LDA
> optimizers (currently EM and Online). Note that only {{SparseVector}}s can be
> empty.
