# Creating DataFrames

With a SparkSession, applications can create DataFrames from an existing RDD, from a Hive table, or from Spark data sources.

As an example, the following creates a DataFrame based on the content of a JSON file:

```
val df = spark.read.json("file:///home/dv6/spark/spark/examples/src/main/resources/people.json")
df.show()
/*
+----+-------+
| age|   name|
+----+-------+
|null|Michael|
|  30|   Andy|
|  19| Justin|
+----+-------+

*/
```
