                 Key: HDFS-2705
                 URL: https://issues.apache.org/jira/browse/HDFS-2705
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 0.24.0, 0.23.1
            Reporter: Alejandro Abdelnur
            Assignee: Alejandro Abdelnur
             Fix For: 0.24.0, 0.23.1


The append/create requests should require 'application/octet-stream' as 
content-type when uploading data. This is to prevent the default content-type 
form-encoded (used as default by some HTTP libraries) to be used or text based 
content-types to be used.

If the form-encoded content type is used, then Jersey tries to process the 
upload stream as parameters
If a test base content-type is used, HTTP proxies/gateways could do attempt 
some transcoding on the stream thus corrupting the data.
