------------------------------------
Summary: LDASuite needs unit tests for empty documents
Key: SPARK-9225
URL: https://issues.apache.org/jira/browse/SPARK-9225
Project: Spark
Issue Type: Test
Components: MLlib
Reporter: Feynman Liang
Priority: Minor
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.
