Chen Liang updated HDFS-11857: ------------------------------ Status: Patch Available (was: Open) > Ozone : need to refactor > StorageContainerLocationProtocolServerSideTranslatorPB > ------------------------------------------------------------------------------- > > Key: HDFS-11857 > URL: https://issues.apache.org/jira/browse/HDFS-11857 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Chen Liang > Assignee: Chen Liang > Attachments: HDFS-11857-HDFS-7240.001.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
