包路径：org.apache.hadoop.hbase.zookeeper.ZKUtil
类名称：ZKUtil
方法名：deleteNodeRecursively

ZKUtil.deleteNodeRecursively介绍

[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。
