> ACCUMULO-2984 introduces an AccumuloStatus checker class that is used to ensure that
the Accumulo instance that MAC is "starting" isn't already running (as the potential for multiple
active masters or tservers is a real, scary possibility).
> When this tool is used as a sanity check that no Accumulo processes are running for an
instance, it would be nice if we could actually get the list of processes on hosts so that
they can be "dealt with". Right now, the user would only know that processes are running,
and would have to check ZK manually or inspect {{ps}} on all nodes, neither of which are ideal.
> Add some sort of logging, or toggle to stdout, to display what nodes are running which
processes when Accumulo is up when the tool is used as a sanity-check for "Accumulo is down".
