Overview
Concrete tool for configuring an HBase client connection through ZooKeeper provided by org.apache.hadoop.hbase.HBaseConfiguration.
Description
The HBaseConfiguration.create() static method returns a Hadoop Configuration object that is pre-initialized with HBase default settings. The returned configuration object is then customized by setting the ZooKeeper quorum hosts and client port, which are the minimum required parameters for an HBase client to locate the cluster.
In the BigData-Notes reference implementation, this configuration is created once inside a static initializer block in HBaseUtils, ensuring it is available for the lifetime of the application.
Usage
Call HBaseConfiguration.create() at application startup, set the ZooKeeper connection properties, and pass the resulting Configuration to ConnectionFactory.createConnection().

Inputs
| Name | Type | Required | Description |
|---|---|---|---|
| (none) | -- | -- | The create() factory method takes no arguments. Configuration properties are set after creation.
|
| hbase.zookeeper.property.clientPort | String | Yes | The port on which ZooKeeper listens for client connections (typically "2181").
|
| hbase.zookeeper.quorum | String | Yes | Comma-separated list of ZooKeeper host names or IP addresses (e.g., "hadoop001" or "zk1,zk2,zk3").
|
Outputs
| Name | Type | Description |
|---|---|---|
| configuration | org.apache.hadoop.conf.Configuration | A Hadoop Configuration object populated with HBase defaults and the specified ZooKeeper connection properties. |
Usage Examples
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
// Create a Configuration pre-loaded with HBase defaults
Configuration configuration = HBaseConfiguration.create();
// Set the ZooKeeper client port
configuration.set("hbase.zookeeper.property.clientPort", "2181");
// Set the ZooKeeper quorum (comma-separated for multi-node ensembles)
configuration.set("hbase.zookeeper.quorum", "hadoop001");
// The configuration is now ready to be passed to ConnectionFactory
