---------------------------
Summary: Extend BlockSender to support multiple block data source
Key: HDFS-8171
URL: https://issues.apache.org/jira/browse/HDFS-8171
Project: Hadoop HDFS
Issue Type: Sub-task
Components: datanode
Reporter: Li Bo
Assignee: Li Bo
Currently BlockSender reads a block from the disk and sends it to a remote
datanode. In EC encode/decode work, new blocks are generated by calculation. In
order to store these blocks to remote datanodes, we can ask BlockSender to read
data from the output of encode/decode calculation.
