Package org.apache.hadoop.http

Class HadoopCoreAuthenticationFilter

java.lang.Object

org.apache.hadoop.security.authentication.server.AuthenticationFilter

org.apache.hadoop.http.HadoopCoreAuthenticationFilter

All Implemented Interfaces:

javax.servlet.Filter

public class HadoopCoreAuthenticationFilter
extends org.apache.hadoop.security.authentication.server.AuthenticationFilter

AuthenticationFilter exposes several configuration params such as AuthenticationFilter.AUTH_TOKEN_VALIDITY. Normally these params go into web.xml. The problem with above is that each webserver (JT/TT/HBase) has to configure these params separately in the corresponding web.xml files. This class overrides the above behavior to get the config params from core-site.xml. All the webservers that depend on hadoop core automatically get a single config defined in core-site.xml. The config in core-site.xml should go like: hadoop.http.authentication.signature.secret - 13048203948239 hadoop.http.authentication.token.validity - 48 The default values are hardcoded in AuthenticationFilter itself.
