Please read this chapter carefully, especially the <<basic.prerequisites,Basic Prerequisites>> to ensure that your HBase testing and deployment goes smoothly, and prevent data loss.

.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.
|
||||
|
||||
Supported::
|
||||
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.
|
||||
|
||||
Tested::
|
||||
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.
