Herein you will find either the definitive documentation on an HBase topic as of its standing when the referenced HBase version shipped, or it will point to the location in Javadoc or JIRA where the pertinent information can be found. The source for this guide can be found in the _src/main/asciidoc directory of the HBase source.This reference guide is marked up using Ascii Doc from which the finished guide is generated as part of the 'site' build target.Run If this is your first foray into the wonderful world of Distributed Computing, then you are in for some interesting times.
Your cluster’s operation can hiccup because of any of a myriad set of reasons from bugs in HBase itself through misconfigurations — misconfiguration of HBase but also operating system misconfigurations — through to hardware problems whether it be a bug in your network card drivers or an underprovisioned RAM bus (to mention two recent examples of hardware issues that manifested as "HBase is slow").
You will also need to do a recalibration if up to this your computing has been bound to a single box.
Here is one good starting point: Fallacies of Distributed Computing.
The phrases /supported/, /not supported/, /tested/, and /not tested/ occur several places throughout this guide.
This is not an appropriate configuration for a production instance of HBase, but will allow you to experiment with HBase.
This section shows you how to create a table in HBase using the CLI, insert rows into the table, perform put and scan operations against the table, enable or disable the table, and start and stop HBase.
Apart from downloading HBase, this procedure should take less than 10 minutes.
Using HBase with a local filesystem does not guarantee durability.
In the interest of clarity, here is a brief explanation of what is generally meant by these phrases, in the context of HBase.
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.
