How to implement web and Security Mechanism in hadoop

This article is about how hadoop implements web plus security mechanisms. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Add the following attributes to the core-site.xml

Hadoop.http.filter.initializers org.apache.hadoop.security.AuthenticationFilterInitializer hadoop.http.authentication.signature.secret.file hadoop-http-auth-signature-secret hadoop.http.authentication.simple.anonymous.allowed false

Create a new hadoop-http-auth-signature-secret file under the hadoop installation directory. Note that the path can be written in hadoop-http-auth-signature-secret, where is the relative path. By default, hadoop is written in the hadoop installation directory, and hadoop is written in the hadoop-http-auth-signature-secret file, which means that you can use hadoop as a user to log in to hadoop's web. Multiple users can be defined and separated by line breaks.

After configuring the relevant attributes, directly access the hadoop web, as shown in the above picture, how can you access it normally? add? user.name=hadoop to the connection and you can access it.
