< h2 > < a name = "Introduction" > < / a > Introduction< / h2 >
< p > This document describes how to configure Hadoop HTTP web-consoles to require user authentication.< / p >
< p > By default Hadoop HTTP web-consoles (ResourceManager, NameNode, NodeManagers and DataNodes) allow access without any form of authentication.< / p >
< p > Hadoop HTTP web-consoles can be configured to require Kerberos authentication using HTTP SPNEGO protocol (supported by browsers like Firefox and Internet Explorer).< / p >
< p > In addition, Hadoop HTTP web-consoles support the equivalent of Hadoop’ s Pseudo/Simple authentication. If this option is enabled, the user name must be specified in the first browser interaction using the user.name query string parameter. e.g. < code > http://localhost:8088/cluster?user.name=babu< / code > .< / p >
< p > If a custom authentication mechanism is required for the HTTP web-consoles, it is possible to implement a plugin to support the alternate authentication mechanism (refer to Hadoop hadoop-auth for details on writing an < code > AuthenticationHandler< / code > ).< / p >
