[jira] [Created] (HADOOP-10941) Proxy user verification NPEs if remote host is unresolvable

Daryn Sharp created HADOOP-10941:
------------------------------------

             Summary: Proxy user verification NPEs if remote host is unresolvable
                 Key: HADOOP-10941
                 URL: https://issues.apache.org/jira/browse/HADOOP-10941
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc, security
    Affects Versions: 3.0.0, 2.5.0
            Reporter: Daryn Sharp
            Priority: Critical


A null is passed to the impersonation providers for the remote address if it is unresolvable.  {{DefaultImpersationProvider}} will NPE, ipc will close the connection immediately (correct behavior for such unexpected exceptions), client fails on {{EOFException}}.
