From C* to DataFrames with JSON

[Jean-Francois Gosselin]

Hi all,

I'm struggling (Spark / Scala newbie) to create a DataFrame from a C* table
but also create a DataFrame from column with json .

e.g. From C* table

| id | jsonData                      |
======================
| 1 |  {"a": "123", "b": "xyz" } |
+--+-------------------------------+
| 2 |  {"a": "3", "b": "bar" }     |


to Spark DataFrame:

| id |  a   |  b   |
===========
| 1 | 123 | xyz |
+--+------+-----+
| 2 | 3     | bar |


I'm using Spark 1.6 .

Thanks


JF
