Best as I can tell, we don't actually have the ability to do this.
We can use external ZooKeeper servers and we can start a MAC instance on
top of an already running ZK from a different MAC instance, but it
doesn't look like we have the ability to reuse the same storage directory.
That sounds like a useful improvement to me. I'm not sure if there are
any edge cases that make this hard (haven't thought enough about it).
Want to open a JIRA issue for it, Sven?

Hi there,
is it possible for MiniAccumuloCluster to reuse a given directory?
Sadly, I haven't found anything in the docs?
I’ll fire up my instance like this:
val dict = new File("/tmp/accumulo-mini-cluster")
val accumulo = new MiniAccumuloCluster(dict, "test“)
If I’ll restart my JVM it will raise a error like this:
Exception in thread "main" java.lang.IllegalArgumentException: Directory
/tmp/accumulo-mini-cluster is not empty
It would be nice if the data can survive a JVM restart and the folder structure
must not be constructed every time.
Thanks a lot!

Sven
