[comment|https://issues.apache.org/jira/browse/HADOOP-2576?focusedCommentId=12561866#action_12561866]
in HADOOP-2576.
Namenode asks a datanode to delete blocks only if datanode is not asked to
transfer a block. Namenode should send both the blocks to transfer and to
delete. The problem gets worse if configured heartbeat is longer.
