----------------------------------
I am reopening this as I feel we need this per the issues

which are loosely or tightly related with this feature in spark-csv.
There are loosely or tightly related and similar questions/issues in spark-xml too for example as below:

> Support for creating a dataframe from CSV in Dataset[String]
> ------------------------------------------------------------
>
> Key: SPARK-15463
> URL: https://issues.apache.org/jira/browse/SPARK-15463
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: PJ Fanning
>
> I currently use Databrick's spark-csv lib but some features don't work with Apache Spark 2.0.0-SNAPSHOT. I understand that with the addition of CSV support into spark-sql directly, that spark-csv won't be modified.
> I currently read some CSV data that has been pre-processed and is in RDD[String] format.
> There is sqlContext.read.json(rdd: RDD[String]) but other formats don't appear to support the creation of DataFrames based on loading from RDD[String].
