Is it possible to run/submit Spark Step synchronously?
I am trying to run the Spark step on AWS EMR cluster from Java App.
I am trying to implement a service that runs the job and returns the results. I am exploring client mode execution of AWS EMR. But not sure if thats the right answer. Any guidance or links would be great help.
High level workflow for api endpoint looks like this.
/getMeStat -> add step to AWS EMR (EMR runs the job, generate result) -> returns results
