Sumit Chawla created SPARK-10835: ------------------------------------ Summary: Change Output of NGram to Array(String, True) Key: SPARK-10835 URL: https://issues.apache.org/jira/browse/SPARK-10835 Project: Spark Issue Type: Improvement Components: ML Reporter: Sumit Chawla Assignee: yuhao yang Priority: Minor Fix For: 1.5.0
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
