+If you wish to use the external shuffle service in a Mesos deployment you
need to launch the

is provided in the `sbin/`

by running

passed in `SPARK_SHUFFLE_OPTS`.

This seems to be the wrong patch to put this. As of the changes here
dynamic allocation is not yet supported in Mesos yet, so it would make more
sense to put this paragraph in your other patch. Otherwise if this patch goes
in first then the docs are a little misleading, especially since in L72 we
explicitly say that DA on Mesos is not supported yet.
