Taobao's distributed file system

Taobao, which is China’s biggest online shopping website similar to Amazon/EBay, just broke the sales record worth $14.3bn in a single day on Nov. 11. It has it’s file system called TFS（Taobao File System), open sourced at http://code.taobao.org/p/tfs/src/

From the description on this Chinese website, I can see it's classic HDFS file system, integrated with Zookeeper's leader selection algorithm for the data nodes, and Hive's myssql metadata store. It also says it's going to integrate with Erasure Code, which I believe is the version just open sourced by Cloudera this September. These Chinese companies are really good at integrating the latest open source technologies, and put it to scale!
