David Medinets commented on ACCUMULO-2739:
------------------------------------------

Just for argument's sake, I'll mention Docker because it is supposed to start nodes in milliseconds.
I know that people use Docker for Hadoop. Has anyone here used Docker?

> Two common griefs about MiniAccumuloCluster is that it's slow to start and it is difficult
to debug things running inside of the Master or TabletServer (because they are in separate
processes).
> Running each Accumulo process inside of the parent process would likely increase startup
speed and would make debugging much easier (as you wouldn't have to remote-attach the debugger
anymore).
> Such a MAC would likely also pave the way for easier migration away from MockAccumulo
as both of the above complaints are some of the primary concerns for removing Mock with no
replacemnt.
