Akira Ajisaka created HADOOP-16454: -------------------------------------- Summary: Share delegation tokens between multiple HttpFS servers Key: HADOOP-16454 URL: https://issues.apache.org/jira/browse/HADOOP-16454 Project: Hadoop Common Issue Type: New Feature Components: httpfs Environment: Kerberized, clients connect to multiple HttpFS servers via load balancer Reporter: Akira Ajisaka
In our environment, multiple HttpFS servers are deployed for the clients outside the HDFS cluster. As we are using external load balancer service for the HttpFS servers, the following situation may happen: 1. A client authenticates with a HttpFS server and gets a delegation token. Using the delegation token, the client can access to the NameNode. 2. In the next session, the client authenticates with another HttpFS server (via load balancer) using the same delegation token. The client fails to access because the other HttpFS server does not have the information of the delegation token. It would be nice to have a feature like HADOOP-14445 in HttpFS to fix the situation. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
