Subject [jira] Created: (HDFS-1461) Refactor hdfs.server.datanode.BlockSender
Date Mon, 18 Oct 2010 21:28:33 GMT
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.
