Description:
Try to apply flatMap() on Dataset column which of of type
com.A.B
Here's a schema of a dataset:
{code}
root
|-- id: string (nullable = true)
|-- outputs: array (nullable = true)
||-- element: string
{code}
flatMap works on RDD
{code}
ds.rdd.flatMap(_.outputs)
{code}
flatMap doesnt work on dataset and gives the following error
{code}
ds.flatMap(_.outputs)
{code}
The exception:
