title: Spark SQL from_json documentation
body: <p>Where can I find more detailed information regarding the schema parameter of the from_json function in Spark SQL? A coworker gave me a schema example that works, but to be honest, I just don't understand and it doesn't look like any of the examples I have found thus far. The documentation found <a href="https://spark.apache.org/docs/latest/api/sql/index.html#from_json" rel="noreferrer">here</a> seems to be lacking.</p>
