Hadoop Web UI控制台添加验证

       默认情况下，Hadoop HTTP Web控制台（ResourceManager，NameNode，NodeManagers和DataNodes）允许访问而无需任何形式的身份验证。

      官网连接：https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/HttpAuthentication.html

1、配置core-site.xml

<configuration>
	<!-- Authentication for Hadoop HTTP web-consoles -->
	<property>
		<name>hadoop.http.filter.initializers</name>
		<value>org.apache.hadoop.security.AuthenticationFilterInitializer</value>
	</property>
	<property>
		<name>hadoop.http.authentication.type</name>
		<value>simple</value>
	</property>
	<property>
		<name>hadoop.http.authentication.token.validity</name>
		<value>3600</value>
	</property>
