[jira] [Created] (HDFS-6581) Write to single replica in memory

Arpit Agarwal created HDFS-6581:
-----------------------------------

             Summary: 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


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.
