Summary: [WRITE] The DatanodeProtocol should be have DNA_BACKUP to
backup blocks
Key: HDFS-13310
URL: https://issues.apache.org/jira/browse/HDFS-13310
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Ewan Higgs
Assignee: Ewan Higgs
As part of HDFS-12090, Datanodes should be able to receive DatanodeCommands in
the heartbeat response that instructs it to backup a block.
This should take the form of two sub commands: PUT_FILE (when the file is <=1
block in size) and MULTIPART_PUT_PART when part of a Multipart Upload (see
HDFS-13186).
