 This chapter expands upon the <<getting_started>> chapter to further explain
configuration of Apache HBase.

 == Configuration Files
 Apache HBase uses the same configuration system as Apache Hadoop.

 To protect existing HBase installations from new vulnerabilities, please *do not* use JIRA

+.Support and Testing Expectations
+The phrases /supported/, /not supported/, /tested/, and /not tested/ occur several
+places throughout this guide. In the interest of clarity, here is a brief explanation
+of what is generally meant by these phrases, in the context of HBase.
+NOTE: Commercial technical support for Apache HBase is provided by many Hadoop vendors.
+This is not the sense in which the term /support/ is used in the context of the
+Apache HBase project. The Apache HBase team assumes no responsibility for your
+HBase clusters, your configuration, or your data.
+  In the context of Apache HBase, /supported/ means that HBase is designed to work
+  in the way described, and deviation from the defined behavior or functionality should
+  be reported as a bug.
+Not Supported::
+  In the context of Apache HBase, /not supported/ means that a use case or use pattern
+  is not expected to work and should be considered an antipattern. If you think this
+  designation should be reconsidered for a given feature or use pattern, file a JIRA
+  or start a discussion on one of the mailing lists.
+  In the context of Apache HBase, /tested/ means that a feature is covered by unit
+  or integration tests, and has been proven to work as expected.
+Not Tested::
+  In the context of Apache HBase, /not tested/ means that a feature or use pattern
+  may or may notwork in a given way, and may or may not corrupt your data or cause
+  operational issues. It is an unknown, and there are no guarantees. If you can provide
+  proof that a feature designated as /not tested/ does work in a given way, please
+  submit the tests and/or the metrics so that other users can gain certainty about
+  such features or use patterns.
