sending data in multiple segments causes s3upload (jets3t) to fail

[Jaseer Tk <jaseer.tk@xxxxxxxxxx>]

Hi,

I am trying to use hadoop distcp while copying data from hdfs to s3. Hadoop distcp devides the data in to multiple chunks and sends the data parellely so that faster performance is achieved. However this is failing against ceph s3 indicating a mismatch between md5 and etag returned by s3. However this is working with aws s3

Is there a workaround for this, apart from setting

storage-service.disable-live-md5=true in jets3t.properties ?

Dont want to disable md5 checking because it will not ensure 

correctness of uploaded data.

Thank you,

Jaseer TK
