Reynold Xin created SPARK-5752:
----------------------------------
Summary: Don't implicitly convert RDDs directly to DataFrames
Key: SPARK-5752
URL: https://issues.apache.org/jira/browse/SPARK-5752
Project: Spark
Issue Type: Sub-task
Reporter: Reynold Xin
DataFrame is a rich API consisting of too many functions. It would be safer to
convert RDDs to a DataFrameHolder that consists of only two functions:
{code}
- toDataFrame()
- toDataFrame(String*)
{code}
This way, it is highly unlikely to have ambiguous implicit conversions, at the
cost of requiring users to always call toDataFrame before being able to use
DataFrame functions.
