Lei (Eddy) Xu commented on HDFS-11987:
--------------------------------------
bq. this API works better if it's implemented server-side for atomicity.
It'd be a nice characteristic to have. But one difficulty of implementing in
this way is that, when {{CREATE|APPEND}} is specified when calling either
create() or append(), they would either return {{HdfsFileStatus}} or
{{LastBlockWithStatus}} from server side, which makes it necessary to change
RPC protocol.
Any thoughts on this?
