无authentication有authorization模式下使用hbase
hbase默认情况下对客户端不做任何权限控制,这对于很多应用场景是不适用的。而kerberos的SASL验证方式比较啰嗦(主要是增加服务端、客户端的认证配置),而且Secure Access to Apache HBase会对性能有%10左右的损失,这对于轻安全重性能的场景下同样不适合。“Simple User Access to Apache HBase”是一种无authentication有authorization的使用模式,我们可以通过对预定义的用户进行授权,而不需要预先做身份验证。这样可以做到不需增加身份验证的配置工作,而对不同用户的访问权限进行控制与隔离。
实验环境:
hbase版本1.0.2
hadoop版本2.7.1
jdk版本 1.7
服务端侧配置
Add the following to the hbase-site.xml file on every server machine in the cluster:
<property>
<name>hbase.security.authentication</name>
<value>simple</value>
</property>
<property>
<name>hbase.security.authorization</name>
<value>true</value>
</property>
<property>
<name>hbase.coprocessor.master.classes</name>
<value>org.apache.hadoop.hbase.security.access.AccessController</value>
</property>
<property>
<name>hbase.coprocessor.region.classes</name>
<value>org.apache.hadoop.hbase.security.access.AccessController</value>
</property>
<property>
<name>hbase.coprocessor.regionserver.classes</name>
<value>org.apache.hadoop.hbase.security.access.AccessController</value>
</property>
客户端侧配置
Add the following to the hbase-site.xml file on every client:
<property>
<name>hbase.security.authentication</name>
<value>simple</value>
</property>
默认即为simple模式,因此不配这个也没关系。
在服务端增加访问用户(即运行客户端进程的当前系统用户)的权限配置,
如,
注意:此处的用户,即为客户端进程运行时进程所属的系统用户。因此没有用户添加的过程,可以直接对用户授权。
