I am using the Java agent in a project that use Apache Spark, the Java program it-self is a Spark driver (same JVM).
Since Apache Spark doesnot implement Open Tracing, I am using Spark listener to log Spark events such as task start, stage start etc... I create spans, which is ok.
But I would like to create another service "spark", is it possible to have 2 services in same JVM ? ("application" and "spark")
