本文主要是介绍【报错-大数据技术-Hbase Ranger】hbase创建、删除（表、命名空间）无权限问题，但是向表put、get、scan数据报错，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1、问题描述
使用hbase shell执行创建命名空间、创建表、插入数据、获取数据、查看数据、删除命名空间、删除表等命令操作，发现可以创建命名空间、创建表、删除命名空间、删除表，但是插入数据、获取数据、查看数据等操作却报没有权限的问题，但是我已在Ranger上赋予用户testuser1对该命名空间的所有权限了。
报错内容如下：
hbase:001:0> create_namespace 'ns3'
Took 0.5417 seconds
hbase:002:0> create 'ns3:t1', 'C1'
