Some issues regarding HDFS federation

[hehaore...@gmail.com]

Hello. I have a version 3.3.4 Hadoop cluster with over a thousand datanodes. I want to use HDFS Router based Federation. May I ask you a few questions. The first question is, is it better to deploy the router on the namenode server or separately? I want to add a set of Namenodes to the existing HDFS cluster, which means there are two namespaces. The second question is that I have used Kerberos, and federation can run normally. When the value of hadoop.http.authentication.type is kerberos, when I access the router's HTTP page, it shows that a username and password are required. How is this set? I have read the introduction to Federation on the Hadoop version 3.3.4 page. If you have any other information, could you please recommend it. Thank you for reading.     从 Windows 版邮件发送   --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@hadoop.apache.org For additional commands, e-mail: user-h...@hadoop.apache.org
