We adopt the basically structure of hdfs raid from Facebook, and we have migrated these feature to our cluster both in hadoop 1.x(0.20.203) and hadoop 2.x(hadoop 2.4) in Sina. We made some change during our development. Here is the theory of Rc code and the structure of hfs raid, besides we compared the efficiency of different Rc code and make a final conclusion.]]>
