I have a List[org.apache.spark.sql.Row]
which I got from a ListBuffer[org.apache.spark.sql.Row]()
How do I turn this into a dataframe?
obviously .toDF (or RDD) does not work...

1you can convert it to RDD by sc.parallelize(your List[Row]). and then you can convert it into dataframe, but not sure what will be the dataframe structure. – Abhi Jul 12 '16 at 06:03

it's still an `RDD[Row]` and won't be converted by `toDF`..... – Zahiro Mor Jul 12 '16 at 10:04

import sqlContext.implicits._ and then use toDF(your column names), on the RDD[T] – Abhi Jul 12 '16 at 10:45
