In reality, you need a fully-distributed configuration to fully test HBase and to use it in real-world scenarios.

In a distributed configuration, the cluster contains multiple nodes, each of which runs one or more HBase daemon.

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.

Pseudo-distributed mode means that HBase still runs completely on a single host, but each HBase daemon (HMaster, HRegion Server, and Zoo Keeper) runs as a separate process: in standalone mode all daemons ran in one jvm process/instance.

By default, unless you configure the This procedure assumes that you have configured Hadoop and HDFS on your local system and/or a remote system, and that they are running and available. The guide on Setting up a Single Node Cluster in the Hadoop documentation is a good starting point.

It builds upon the previous quickstart, Pseudo-Distributed Local Install, assuming that the system you configured in that procedure is now The next chapter, configuration, gives more information about the different HBase run modes, system requirements for running HBase, and critical configuration areas for setting up a distributed HBase cluster.

This chapter expands upon the Getting Started chapter to further explain configuration of Apache HBase.

Instead, send your report to the mailing list [email protected], which allows anyone to send messages, but restricts who can read them.

Someone on that list will contact you to follow up on your report.

These include primary and backup Master instances, multiple Zoo Keeper nodes, and multiple Region Server nodes.
