本文整理了Java中org.apache.hadoop.hbase.HBaseTestingUtility.getHBaseAdmin()方法的一些代码示例，展示了HBaseTestingUtility.getHBaseAdmin()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。HBaseTestingUtility.getHBaseAdmin()方法的具体详情如下：
包路径：org.apache.hadoop.hbase.HBaseTestingUtility
类名称：HBaseTestingUtility
方法名：getHBaseAdmin

HBaseTestingUtility.getHBaseAdmin介绍

[英]Returns a Admin instance. This instance is shared between HBaseTestingUtility instance users. Closing it has no effect, it will be closed automatically when the cluster shutdowns
[中]返回一个管理实例。此实例在HBaseteStangulity实例用户之间共享。关闭它无效，当群集关闭时，它将自动关闭
