> URL: https://issues.apache.org/jira/browse/SPARK-8277
> Project: Spark

>
> For example calling `createDataFrame` on the data from
> http://s3-us-west-2.amazonaws.com/sparkr-data/flights.csv takes a really long
> time
> This is mainly because we try to convert a DataFrame to a List in order to
> parallelize it by rows and the conversion from DF to list is very slow for
> large data frames.
