public static boolean usingJanus()

allocateSparkPort

public static void allocateSparkPort(ai.grakn.engine.GraknConfig config)

Allocates an unused port for Spark.

This should always be called immediately before Spark starts in order to minimise a potential race condition: in between finding an unused port and starting Spark, something else may steal the same port.

The correct way to solve this race condition is to specify the Spark port as 0. Then, Spark will allocate the port itself. However, there is an issue where Service.port() will always report 0 even after Spark has started.
