----------------------------------------
Summary: Add RDD methods to DataFrame to preserve schema
Key: SPARK-6292
URL: https://issues.apache.org/jira/browse/SPARK-6292
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 1.3.0
Reporter: Joseph K. Bradley
Users can use RDD methods on DataFrames, but they lose the schema and need to
reapply it. For RDD methods which preserve the schema (such as randomSplit),
DataFrame should provide versions of those methods which automatically preserve
the schema.
