I'll include a prototype patch by next week. > Write to single replica in memory > --------------------------------- > > Key: HDFS-6581 > URL: https://issues.apache.org/jira/browse/HDFS-6581 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: datanode > Reporter: Arpit Agarwal > Assignee: Arpit Agarwal > Attachments: HDFSWriteableReplicasInMemory.pdf > > > Per discussion with the community on HDFS-5851, we will implement writing to > a single replica in DN memory via DataTransferProtocol. > This avoids some of the issues with short-circuit writes, which we can > revisit at a later time. -- This message was sent by Atlassian JIRA (v6.2#6252)
