Mirror Maker 2 MirrorClient

All:
I was tinkering around with the MirrorClient and was curious about the
configs. I see that I can use the MirrorMaker config to pull in the same
configs that were used to spin up the MM2 cluster. Seeing as MM2 is started
with these configs in a property file and it is passed in on command line,
I take it is implying that I should read the same file to set up my
MirrorClient application to then feed into MirrorMakerConfig, to the get
the clientConfig like in the code comments? Or am I reading too much into
this and just configure for the cluster I am setting up the Client for?

thanks,
Carl
