How to use hbase with Spring Boot using Java instead of XML?

Question

I have Spring Boot Hadoop and want to take advantage of the Spring HbaseTemplate. My issue is the documentation has only information about the \"xml\" way of the configurati

Even though a Java-based configuration for HBase is yet not formally available (as recently as Spring Hadoop 2.2.1), there is a clean workaround. Include the relevant ZooKeeper details as properties within a Java-based Spring Hadoop configuration. Then, the hbase-configuration XML tag need not include any configuration details. By convention, it will depend on the hadoopConfiguration bean defined by the Java-based HadoopConfigConfigurer.

@Configuration
@EnableHadoop
public class MapReduceConfiguration extends SpringHadoopConfigurerAdapter {
    @Override
    public void configure(HadoopConfigConfigurer config) throws Exception {
        config
                .fileSystemUri(myConfigManager.getHadoopFsUri())
                .resourceManagerAddress(myConfigManager.getHadoopResourceManagerAddress())
                .withProperties()
                .property("hbase.zookeeper.quorum", myConfigManager.getZookeeperQuorum())
                .property("hbase.zookeeper.property.clientPort", myConfigManager.getZookeeperPort())
                .property("hbase.client.scanner.caching", "1");
    }
}

The remaining XML configuration is agnostic to the deployment environment:
