problem using top level s3 buckets as input/output directories
--------------------------------------------------------------

                 Key: HADOOP-5805
                 URL: https://issues.apache.org/jira/browse/HADOOP-5805
             Project: Hadoop Core
          Issue Type: Bug
          Components: fs/s3
    Affects Versions: 0.18.3
         Environment: ec2, cloudera AMI, 20 nodes
            Reporter: Arun Jacob


When I specify top level s3 buckets as input or output directories, I get the following exception.

hadoop jar subject-map-reduce.jar s3n://infocloud-input s3n://infocloud-output

java.lang.IllegalArgumentException: Path must be absolute: s3n://infocloud-output

The workaround is to specify input/output buckets with sub-directories:

 
hadoop jar subject-map-reduce.jar s3n://infocloud-input/input-subdir  s3n://infocloud-output/output-subdir
