Nick Dimiduk resolved HBASE-24271.
----------------------------------
Release Note:
<!-- markdown -->
HBASE-24271 makes changes the the default `conf/hbase-site.xml` such that
`bin/hbase` will run directly out of the binary tarball or a compiled source
tree without any configuration modifications vs. Hadoop 2.8+. This changes our
long-standing history of shipping no configured values in
`conf/hbase-site.xml`, so existing processes that assume this file is empty of
configuration properties may require attention.
Resolution: Fixed
> Set values in `conf/hbase-site.xml` that enable running on `LocalFileSystem`
> out of the box

> This ticket is to implement the changes as described on the [discussion on
> dev|https://lists.apache.org/thread.html/r089de243a9bc9d923fa07c81e6bc825b82be68f567b892a342a0c61f%40%3Cdev.hbase.apache.org%3E].
> It reverts and supersedes changes made on HBASE-24086 and HBASE-24106.
> {quote}
> The conclusion I understand from this thread looks something like this:
> 1. revert HBASE-24086, make it so that running on `LocalFileSystem` is a
> fatal condition with default configs.
> 2. ship a conf/hbase-site.xml that contains
> hbase.unsafe.stream.capability.enforce=false, along with a big comment saying
> this is not safe for production.
> 3. ship a conf/hbase-site.xml that contains hbase.tmp.dir=./tmp, along with a
> comment saying herein you'll find temporary and persistent data, reconfigure
> for production with hbase.rootdir pointed to a durable filesystem that
> supports our required stream capabilities (see above).
> 4. update HBASE-24106 as appropriate.
> Neither 2 nor 3 are suitable for production deployments, thus the changes do
> not go into hbase-default.xml. Anyone standing up a production deploy must
> edit hbase-site.xml anyway, so this doesn't change anything. It also restores
> our "simple" first-time user experience of not needing to run anything
> besides `bin/start-hbase.sh` (or `bin/hbase master start`, or whatever it is
> we're telling people these days).
> We can reassess this once more when a durable equivalent to LocalFileSystem
> comes along.
