Chen Liang updated HDFS-11857:
------------------------------
Resolution: Not A Problem
Status: Resolved (was: Patch Available)
We decided to make the separation done, filed HDFS-11859 to track the protocol
separation work. With separation done, this JIRA's issue no longer exist.

> Currently, StorageContainerLocationProtocolServerSideTranslatorPB has two
> protocol impls:
> {{StorageContainerLocationProtocol impl}}
> {{ScmBlockLocationProtocol blockImpl}}.
> the class provides container-related services by invoking {{impl}}, and
> block-related services by invoking {{blockImpl}}. Namely, on server side, the
> implementation makes a distinguish between "container protocol" and "block
> protocol".
> An issue is that, currently, everywhere except for the server side is viewing
> "container protocol" and "block protocol" as different. More specifically,
> StorageContainerLocationProtocol.proto still includes both container
> operation and block operation in itself alone. As a result of this
> difference, it is difficult to implement certain APIs (e.g. putKey) properly
> from client side.
> This JIRA merges "block protocol" back to "container protocol" in
> StorageContainerLocationProtocolServerSideTranslatorPB, to unblock the
> implementation of other APIs for client side.
> Please note that, in the long run, separating these two protocols does seem
> to be the right way. This JIRA is only a temporary solution to unblock
> developing other APIs. Will need to revisit these protocols in the future.
> Thanks [~xyao] for the offline discussion.
