This is the meat of the whole problem. We'll allocate a port for a given slave, transformation and step copy, always on the same host. Algorithm: 1) Search for the right map in the hostPortMap

Parameters:

portRangeStart - the start of the port range as described in the used cluster schema

hostname - the host name to allocate this address for

clusteredRunId - A unique id, created for each new clustered run during transformation split.

transformationName -

sourceStepName -

sourceStepCopy -

Returns:
