In reality, you need a fully-distributed configuration to fully test HBase and to use it in real-world scenarios.
Script for Windows and Linux / Unix environments to set up the working environment for HBase, including the location of Java, Java options, and other environment variables.
The file contains many commented-out examples to provide guidance.
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.
These include primary and backup Master instances, multiple Zoo Keeper nodes, and multiple Region Server nodes.
This quickstart assumes that each node is a virtual machine and that they are all on the same network.
You must be able to connect to all nodes via SSH, including the local node, from the Master as well as any backup Master, using a shared key rather than a password.
