I have a supposedly simple problem that I've been stuck on for a while. My DataFrame has this schema:
root
|-- _id: string (nullable = true)
|-- created: timestamp (nullable = true)
|-- geometry: struct (nullable = true)
| |-- coordinates: string (nullable = false)
| |-- type: string (nullable = false)
How do I extract the 'coordinates' and 'type' strings? (I know they shouldn't be strings but I'm looking to change them after isolating)
I'm using Databricks 3.0, Spark 2.2. Thank you!
