Hi all

I am testing s3n file system facilities and try to copy from hdfs to S3 in
original format

And I get next errors

    Are you using 0.18? I know that the copy HDFS to s3n isn't supported there
    yet. I think there's a fix in 0.19.

    I'm thinking of this bug:
    http://issues.apache.org/jira/browse/HADOOP-3361

    It was the cause of problems I hit trying to copy from HDFS to S3N with
    0.18.1.
