[jira] Created: (HADOOP-6907) Rpc client doesn't use the
per-connection conf to figure out server's Kerberos principal
Rpc client doesn't use the per-connection conf to figure out server's Kerberos principal
----------------------------------------------------------------------------------------
Key: HADOOP-6907
URL: https://issues.apache.org/jira/browse/HADOOP-6907
Project: Hadoop Common
Issue Type: Bug
Components: ipc, security
Reporter: Kan Zhang
Assignee: Kan Zhang
Currently, RPC client caches the conf that was passed in to its constructor and uses that same conf (or values obtained from it) for every connection it sets up. This is not sufficient for security since each connection needs to figure out server's Kerberos principal on a per-connection basis. It's not reasonable to expect the first conf used by a user to contain all the Kerberos principals that her future connections will ever need. Or worse, if her first conf contains an incorrect principal name, it will prevent the user from connecting to the server even if she later on passes in a correct conf on retry (RPC.getProxy()).
