Subject [jira] [Created] (HADOOP-9358) "Auth failed" log should include exception string
Date Mon, 04 Mar 2013 22:41:13 GMT
Todd Lipcon created HADOOP-9358:
-----------------------------------

             Summary: "Auth failed" log should include exception string
                 Key: HADOOP-9358
                 URL: https://issues.apache.org/jira/browse/HADOOP-9358
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc, security
    Affects Versions: 3.0.0, 2.0.4-beta
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


Currently, when authentication fails, we see a WARN message like:
{code}
2013-02-28 22:49:03,152 WARN  ipc.Server (Server.java:saslReadAndProcess(1056)) - Auth failed
for 1.2.3.4:12345:null
{code}
This is not useful to understand the underlying cause. The WARN entry should additionally
include the exception text, eg:
{code}
2013-02-28 22:49:03,152 WARN  ipc.Server (Server.java:saslReadAndProcess(1056)) - Auth failed
for 1.2.3.4:12345:null (GSS initiate failed [Caused by GSSException: Failure unspecified at
GSS-API level (Mechanism level: Request is a replay (34))])
{code}
