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.You can see the basic methodology for such a set-up in Linux or Unix systems at "Procedure: Configure Passwordless SSH Access".If your cluster nodes use OS X, see the section, SSH: Setting up Remote Desktop and Enabling Self-Login on the Hadoop wiki.HBase uses the local hostname to self-report its IP address.
For most configurations, a restart is needed for servers to pick up changes.
instance has all HBase daemons — the Master, Region Servers, and Zoo Keeper — running in a single JVM persisting to the local filesystem. We will show you how to create a table in HBase using the Prior to HBase 0.94.x, HBase expected the loopback IP address to be 127.0.0.1.
Ubuntu and some other distributions default to 127.0.1.1 and this will cause problems for you. for detail After working your way through quickstart standalone mode, you can re-configure HBase to run in pseudo-distributed mode.
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.
