Michael Stack commented on HBASE-24271:
---------------------------------------

Just had a thought that these changes in hbase-site actually belong in hbase-default.

> 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.

> 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.
