> Issue Type: Bug
> Components: security
> Affects Versions: 2.2.0
> Environment: hadoop-1.0.0;MIT kerberos;java 1.6.0_26
> CDH4.3.0(hadoop 2.0.0-alpha);MIT kerberos;java 1.6.0_26

> With Kerberos enabled, any job that is taking as input or output s3 files
> fails.
> It can be easily reproduced with wordcount shipped in hadoop-examples.jar and
> a public S3 file:
> {code}
> /opt/hadoop/bin/hadoop --config /opt/hadoop/conf/ jar
> /opt/hadoop/hadoop-examples-1.0.0.jar wordcount s3n://ubikodpublic/test out01
> {code}
> returns:
