1.Hbase单机伪集群搭建

拉取镜像

docker pull harisekhon/hbase

启动容器

docker run -d -h docker-hbase \
        -p 2181:2181 \
        -p 8099:8080 \
        -p 8085:8085 \
        -p 9090:9090 \
        -p 9000:9000 \
        -p 9095:9095 \
        -p 16000:16000 \
        -p 16010:16010 \
        -p 16201:16201 \
        -p 16301:16301 \
        -p 16020:16020\
        --name hbase \
        harisekhon/hbase

设置host

在服务的host文件中设置如下映射
127.0.0.1 docker-hbase

访问测试

http://localhost:16010/master-status

进入容器

docker exec -it hbase /bin/bash

基本命令

创建表
	create 'table1' , 'cf1'
删除表
	 disable 't1'
	 drop 't1'
查看表结构
	 describe 't1'
全表扫描
	scan 'test2'
统计表行数
	 count  'OPC_TEST'
查看表信息
	desc  'OPC_TEST'
列出所有命名空间
	 list_namespace 
查看命名空间下的表
	list_namespace_tables 'default'
查看命名空间
	describe_namespace 'hbase'
直接进入hbase shell
	docker exec -ti hbase1 /hbase/bin/hbase shell

全表扫描，匹配rowkey的前缀
	scan 'OPC_TEST',{FILTER=>"RowFilter(=,'substring:1122XZI8904S')"}
显示rowkey字节顺序大于002的键值对
	scan 'OPC_TEST',FILTER=>"RowFilter(>,'binary:002')"
扫描前缀为001的rowkey
	scan 'OPC_TEST',FILTER=>"PrefixFilter('001')"
按时间戳
	scan 'OPC_TEST',{COLUMNS=> 'OPC_COLUMNS',TIMERANGE =>[1592464809160,1592464809166]}
扫描全表，查询指定时间范围和匹配rowkey前缀
	scan 'OPC_TEST',{COLUMNS=> 'OPC_COLUMNS',TIMERANGE =>[1592464809160,1592464809166],FILTER=>"RowFilter(=,'substring:118883XHZ9904S')"}

2.Springboot 整合 HBase客户端

引入pom

**注意jar包版本和服务器的对应关系
这里服务器版本是2.1.3，jar包是2.1.1

  org.apache.hbase
    hbase-client
    2.1.1
     
       
            javax.servlet
            servlet-api
        
    

application.yml中增加配置

## HBase 配置
hbase:
  config:
    hbase.zookeeper.quorum: xx.x.x.xx
    hbase.zookeeper.port: 2181
    hbase.zookeeper.znode: /hbase
    hbase.client.keyvalue.maxsize: 1572864000

配置类

@Data
@ConfigurationProperties(prefix = "hbase")
public class HbaseProperties {
	
    private Map config;
}

@Configuration
@EnableConfigurationProperties(HbaseProperties.class)
public class HbaseConfig {
	
	private final HbaseProperties properties;
	
	public HbaseConfig(HbaseProperties properties) {
		this.properties = properties;
	}
 
	@Bean
	public org.apache.hadoop.conf.Configuration configuration() {
		
		org.apache.hadoop.conf.Configuration configuration = HBaseConfiguration.create();
		
		Map config = properties.getConfig();
		
		Set keySet = config.keySet();
		for (String key : keySet) {
			configuration.set(key, config.get(key));
		}
		return configuration;
	}
}

Hbase工具类

@Slf4j
@Component
@DependsOn("hbaseConfig")

	@Autowired

	private static Admin admin = null;
	
	public static Configuration conf=null;

	@PostConstruct
	private void init() {

		}
		
		try {
		 	connection = ConnectionFactory.createConnection(config.configuration());
			admin = connection.getAdmin();
		} catch (IOException e) {
			log.error("HBase create connection failed: {}", e);
		}
