本文整理了Java中org.apache.hadoop.hbase.zookeeper.ZKUtil.deleteNodeRecursively()
方法的一些代码示例,展示了ZKUtil.deleteNodeRecursively()
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。ZKUtil.deleteNodeRecursively()
方法的具体详情如下:
包路径:org.apache.hadoop.hbase.zookeeper.ZKUtil
类名称:ZKUtil
方法名:deleteNodeRecursively
[英]Delete the specified node and all of it's children.
If the node does not exist, just returns.
Sets no watches. Throws all exceptions besides dealing with deletion of children.
[中]删除指定的节点及其所有子节点。
如果节点不存在,只返回。
没有手表。抛出除处理删除子项之外的所有异常。

发出时Delete对于 hbase,我知道它不会立即删除数据。但是什么时候删除数据,我的意思是,物理上? 最佳答案 当您向 HBase 写入内容时,它会存储在内存存储 (RAM) 中,然后再写入磁盘。
