Re: Hbase first run problem
Taking this into dev.
Should we do something smarter than failing this way even tho it is clearly
written to not create that folder? Like, if the version file doesn't exist
BUT that folder is empty, continue anyway with the bootstrap.

Yes. In fact, its probably safe-to-do now we've left far behind the
pre-history versions of hbase where there was no hbase.version file in the
hbase.rootdir. If absent, lets proceed and just write it rather than treat
it as a non-migrated instance. Want to open an issue jd?
