A Tale of Two Erasure Codes in HDFS

Mingyuan Xia, Mohit Saxena, Mario Blaum, David Pease
2015 USENIX Conference on File and Storage Technologies  
In this paper, we present HACFS, a new erasure-coded storage system that instead uses two different erasure codes and dynamically adapts to workload changes.  ...  It uses a fast code to optimize for recovery performance and a compact code to reduce the storage overhead.  ...  Similarly, HACFS migrates data between fast and compact erasure codes, however with the objective to reduce extra network transfers for recovery in distributed storage.  ...
