我想练习hbase的java api
请问下配置文件该如何配置？
我的配置文件：
data:
hbase:
quorum: 118.25.60.230:2181
rootDir: /home/softs/hbase/data
nodeParent: /hbase
测试类
public static Configuration conf = HBaseConfiguration.create();
@Test
public static void main(String[] args) throws Exception {
System.setProperty("hadoop.home.dir", "/home/hadoop");
HBaseAdmin hBaseAdmin = new HBaseAdmin(conf);
TableName[] tableNames = hBaseAdmin.listTableNames();
for (TableName tableName :
tableNames) {
System.out.println(tableName.toString());
}
}
但是连接不上，请求老师帮助

同学你好：
看打印的日志是 Windows 系统吧，路径格式肯定是不对的。可以搜下 Windows 上 Hbase 的运行方法。
欢迎来 QQ 群随时交流、讨论，也非常感谢同学的支持！
