-----------------------------------
Summary: VectorAssembler should have handleInvalid to handle
columns with null values
Key: SPARK-23690
URL: https://issues.apache.org/jira/browse/SPARK-23690
Project: Spark
Issue Type: Sub-task
Components: ML
Affects Versions: 2.3.0
Reporter: yogesh garg
VectorAssembler only takes in numeric (and vectors (of numeric?)) columns as an
input and returns the assembled vector. It currently throws an error if it sees
a null value in any column. This behavior also affects `RFormula` that uses
VectorAssembler to assemble numeric columns.
