我在使用java连接到kubernetes gcp群集中的远程hbase服务器时遇到一些问题。这是我为测试连接而编写的代码。

Configuration config = HBaseConfiguration.create();
    try {
        config.set("hbase.zookeeper.quorum", "34.xx.xxx.109");
        HBaseAdmin.checkHBaseAvailable(config);
        Connection connection = ConnectionFactory.createConnection(config);
        table = connection.getTable(TableName.valueOf("table_name"));
    } catch (IOException e) {
        e.printStackTrace();
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
    }

但是当 HBaseAdmin.checkHBaseAvailable(config); 在引发以下异常时执行：

org.apache.hadoop.hbase.MasterNotRunningException: java.net.UnknownHostException: can not resolve hbase-74fbxxx579-nglz6,16000,1603123848632

我不知道可能是什么我已经编写了以下python代码，它可以工作，所以可能我缺少一些hbaseconfiguration属性，但我非常关心python与java实现之间的连接有多简单：

import happybase
from datetime import date
connection = happybase.Connection('34.xx.xxx.109')
def main():
  today = date.today()
  table = connection.table('table_name')
  format_today = today.strftime('%Y-%m-%d')
  for key, data in table.scan(row_prefix='prefix_to_search'.encode()):
    print(key, data)
main()
