---------------------------------------
Summary: UGI HadoopLoginModule doesn't catch & wrap all
kerberos-related exceptions
Key: HADOOP-11117
URL: https://issues.apache.org/jira/browse/HADOOP-11117
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.5.1
Reporter: Steve Loughran
Priority: Minor
If something is failing with kerberos login,
{{UserGroupInformation.loginUserFromKeytabAndReturnUGI()}} should fail with
useful information. But not all exceptions from the inner code are caught and
converted to LoginException. Those exceptions that aren't wrapped have their
text and stack trace lost somewhere in the javax code, leaving on the text
"login failed" and a stack trace of no value whatsoever.
