-------------------------------
bq. However, I have no idea about HBase's commitment to IA.Public class across
major releases.
[~liuml07]
We are allowed break compat in a major release (as per semver) but we try to
minimize breakage if only to avoid pissing off our users too much. Can remove
after deprecating for the life of a major release is allowed.
Yeah, [~Apache9] has a point (unfortunately. Public is a bit of a pain. Would
be sweet if could deprecate in master branch too. And yeah, this change even
though in old HBTU has value. Thanks.

> Currently there are 13 {{startMiniCluster()}} methods to set up a mini
> cluster. I'm not surprised if we have a few more in future. It's good to
> support different combination of optional parameters. We have to pick up one
> of them carefully while still wondering the default values of other
> parameters; if we add a new option, we may bring more new methods.
> One solution is to use builder pattern: create a class {{MiniClusterOptions}}
> along with a static class {{MiniClusterOptionsBuilder}}, create a new method
> {{startMiniCluster(MiniClusterOptions)}}. In {{master}} we delete the old 13
> methods while in branch-2, we deprecate the old 13 methods.
> Thoughts?
