------------------------------------

             Summary: Set values in `conf/hbase-site.xml` that enable running on `LocalFileSystem` out of the box
                 Key: HBASE-24271
                 URL: https://issues.apache.org/jira/browse/HBASE-24271
             Project: HBase
          Issue Type: Task
    Affects Versions: 3.0.0, 2.3.0
            Reporter: Nick Dimiduk
            Assignee: Nick Dimiduk


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.
