Xiangrui Meng created SPARK-16074: ------------------------------------- Summary: Expose VectorUDT/MatrixUDT in a public API Key: SPARK-16074 URL: https://issues.apache.org/jira/browse/SPARK-16074 Project: Spark Issue Type: New Feature Components: MLilb Affects Versions: 2.0.0 Reporter: Xiangrui Meng Priority: Critical
Both VectorUDT and MatrixUDT are private APIs, because UserDefinedType itself is private in Spark. However, in order to let developers implement their own transformers and estimators, we should expose both types in a public API to simply the implementation of transformSchema, transform, etc. Otherwise, they need to get the data types using reflection. Note that this doesn't mean to expose VectorUDT/MatrixUDT classes. We can just have a method or a static value that returns VectorUDT/MatrixUDT instance with DataType as the return type. -- 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
