Ewan Higgs commented on HDFS-13936:
-----------------------------------
If there anything in the contract of HDFS specifying that it must fail when
concatting empty files? If so, is it a bad idea to allow this behaviour?
> multipart upload to HDFS to support 0 byte upload

> Key: HDFS-13936
> URL: https://issues.apache.org/jira/browse/HDFS-13936
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: fs, hdfs
> Affects Versions: 3.2.0
> Reporter: Steve Loughran
> Assignee: Ewan Higgs
> Priority: Major
>
> MPUs to HDFS fail as you can't concat an empty block.
> Whatever uploads to HDFS needs to recognise that specific case "0-byte file"
> and rather than try and concat things, just create a 0-byte file there.
> Without this, you can't use MPU as a replacement for distcp or alternative
> commit protocols.
