yuhao yang commented on SPARK-15944: ------------------------------------ This looks practical. Just want to check if this is a temporary behavior that will be deprecated in this or next release. If so, we should add notes to remind users. > Make spark.ml package backward compatible with spark.mllib vectors > ------------------------------------------------------------------ > > Key: SPARK-15944 > URL: https://issues.apache.org/jira/browse/SPARK-15944 > Project: Spark > Issue Type: Umbrella > Components: ML, MLlib > Affects Versions: 2.0.0 > Reporter: Xiangrui Meng > Assignee: Xiangrui Meng > Priority: Critical > > During QA, we found that it is not trivial to convert a DataFrame with old > vector columns to new vector columns. So it would be easier for users to > migrate their datasets and pipelines if we: > 1) provide utils to convert DataFrames with vector columns > 2) automatically detect and convert old vector columns in ML pipelines > This is an umbrella JIRA to track the progress. -- 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
