注意:实践过程中并不需要winutils.exe.
HBase安装请参考:https://blog.youkuaiyun.com/xiaof22a/article/details/80213064
1. 打开Eclipse, 新建工程HBase
2. 将%HBASE_HOME%\lib文件下的所有lib文件添加到 HBase的dependencies中:

3. 测试代码:
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HColumnDescriptor;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.client.HBaseAdmin;
public class Test {
public static Configuration conf = null;
public static void main(String[] args) throws Exception {
conf = HBaseConfiguration.create();
conf.set("hbase.zookeeper.quorum", "master");// 使用eclipse时必须添加这个,否则无法定位
conf.set("hbase.zookeeper.property.clientPort", "2181");
HBaseAdmin admin = new HBaseAdmin(conf);// 新建一个数据库管理员//新api
String[] familys=new String[] {"cf1"};
String tableName="blog";
if (admin.tableExists(tableName)) {
System.out.println("table already exists!");
} else {
HTableDescriptor tableDesc = new HTableDescriptor(tableName);
for (int i = 0; i < familys.length; i++) {
tableDesc.addFamily(new HColumnDescriptor(familys[i]));
}
admin.createTable(tableDesc);
System.out.println("create table " + tableName + " ok.");
}
}
}
输出结果:

本文介绍如何在Eclipse环境中搭建HBase开发环境,并通过示例代码演示如何创建HBase表。具体步骤包括配置HBase依赖、设置Zookeeper参数及使用HBaseAdmin API创建表。
