[jira] [Created] (SPARK-9062) Change output type of Tokenizer to
Array(String, true)
yuhao yang created SPARK-9062:
---------------------------------
Summary: Change output type of Tokenizer to Array(String, true)
Key: SPARK-9062
URL: https://issues.apache.org/jira/browse/SPARK-9062
Project: Spark
Issue Type: Improvement
Components: ML
Reporter: yuhao yang
Priority: Minor
Currently output type of Tokenizer is Array(String, false), which is not compatible with Word2Vec and Other transformers since their input type is Array(String, true). Seq[String] in udf will be treated as Array(String, true) by default.
I'm also thinking for Nullable columns, maybe tokenizer should return Array(null) for null value in the input.
