[jira] Created: (HDFS-1461) Refactor hdfs.server.datanode.BlockSender

Refactor hdfs.server.datanode.BlockSender
-----------------------------------------

                 Key: HDFS-1461
                 URL: https://issues.apache.org/jira/browse/HDFS-1461
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
            Reporter: Ramkumar Vadali


BlockSender provides the functionality to send a block to a data node. But the current implementation requires the source of the block to be a data node. The RAID contrib project needs the functionality of sending a block to a data node, but cannot use hdfs.server.datanode.BlockSender because the constructor requires a datanode object.

https://issues.apache.org/jira/browse/MAPREDUCE-2132 provides the motivation for this.

The purpose of this jira is to refactor hdfs.server.datanode.BlockSender to have another constructor that does not need a DataNode object.
