I am looking for some resources/tutorials that will help me achive this:
My JavaSchemaRDD is from JSON objects like below.

I can call from sql that returns one result array that is a positional
aggregate across all the arrays of matching json objects that are in the select.
{
"vectorId": "7d27f49e-6388-11e4-9fe2-001f29ebd7e2",
"vectorData": [
