[jira] Created: (HADOOP-6982) RPC "relogin" behavior should not be limited to global "login user"

RPC "relogin" behavior should not be limited to global "login user"
-------------------------------------------------------------------

                 Key: HADOOP-6982
                 URL: https://issues.apache.org/jira/browse/HADOOP-6982
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc, security
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon


HADOOP-6706 added an automatic relogin and retry to the RPC connection mechanism in order to avoid "Request is a replay" errors when multiple daemons try to use the same Kerberos principal. It only does so, however, if the connecting user is the "login user". This is problematic for applications which do not use the global "login user" functionality but still need to take advantage of the retries.
