> Inspired by HDFS-12682,  I found the system erasure coding policy state will  
> not  be correctly saved and loaded in a real cluster.  Through there are such 
> kind of unit tests and all are passed with MiniCluster. It's because the 
> MiniCluster keeps the same static system erasure coding policy object after 
> the NN restart operation.
