-------------------------------------
Summary: Naive Bayes should output attributes in predictions
Key: SPARK-14076
URL: https://issues.apache.org/jira/browse/SPARK-14076
Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 2.0.0
Reporter: Xiangrui Meng
In naive Bayes, we outputs predicted labels without feature attributes. So from
the metadata, we can only tell that it is a nominal feature but the values are
missing. We should copy the attributes from input label column to output
prediction column.
