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.
