-----------------------------------
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}
