[jira] [Created] (SPARK-12779) StringIndexer should handle null

Feynman Liang created SPARK-12779:
-------------------------------------

             Summary: StringIndexer should handle null
                 Key: SPARK-12779
                 URL: https://issues.apache.org/jira/browse/SPARK-12779
             Project: Spark
          Issue Type: Bug
          Components: ML
    Affects Versions: 1.6.0
            Reporter: Feynman Liang


StringIndexer currently fails with a {{NullPointerException}} when indexing a column containing {{null}}s. It should instead index all {{null}}s into some sentinel value (say -1).
