Xiangrui Meng created SPARK-15944:
-------------------------------------
Summary: 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.
