HadoopLoginModule的login()方法是一个空函数,只打印了一行调试日志 LOG.debug("hadoop login"); commit()方法负责把Principal添加到Subject中。 此时一个首要问题是username是什么? 在使用了kerberos的情况下,从javax.security.auth.kerberos.KerberosPrincipal的实例获取username。

本篇是为了安装kerberos对hdfs&yarn认证配置的过程,hadoop的集群安装hadoop集群配置已经涵盖不在此篇赘述。 希望读者可以通读全篇之后加上自己的理解然后参照进行配置。 本篇完全借鉴相关博主配置,在此基础上补充路径,添加配置等操作,更加详细以便日后配置学习之用,参考链接放到文章末尾。
