Xiao Chen resolved HDFS-12686.
------------------------------
Resolution: Duplicate
Since HDFS-12682 should be able to handle this, and it's pretty hard to split
that work into 2 jiras due to protobuf changes, I'll resolve this as a dup.
Thanks Sammi for filing the jira and Wei-Chiu for checking!

> Project: Hadoop HDFS

> 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.
