Datanode磁盘大小的说明:
The maximum acceptable size will vary depending upon how large average block size is. The DN’s scalability limits are mostly a function of the number of replicas per DN, not the overall number of bytes stored. That said, having ultra-dense DNs will affect recovery times in the event of machine or rack failure. Cloudera does not support exceeding 100 TB per data node. You could use 12 x 8 TB spindles or 24 x 4TB spindles. Cloudera does not support drives larger than 8 TB.
