Subject [jira] [Created] (HADOOP-14423) s3guard will set file length to -1 on a putObjectDirect(stream, -1) call

Steve Loughran created HADOOP-14423:
---------------------------------------

             Summary: s3guard will set file length to -1 on a putObjectDirect(stream, -1)
call
                 Key: HADOOP-14423
                 URL: https://issues.apache.org/jira/browse/HADOOP-14423
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.0.0-alpha3
            Reporter: Steve Loughran


You can pass a negative number into {{S3AFileSystem.putObjectDirect}}, which means "put until
the end of the stream". S3guard has been using this {{len}} argument: it needs to be using
the actual number of bytes uploaded. Also relevant with client side encryption, when the amount
of data put > the amount of data in the file or stream.

Noted in the committer branch after I added some more assertions, I've changed it there so
making changes to S3AFS.putObjectDirect to pull the content length to pass in to finishedWrite()
from the {{PutObjectResult}} instead. This can be picked into the s3guard branch
