[jira] [Created] (HDFS-12686) Erasure coding system policy state is not correctly saved and loaded during real cluster restart

SammiChen created HDFS-12686:
--------------------------------

             Summary: Erasure coding system policy state is not correctly saved and loaded during real cluster restart
                 Key: HDFS-12686
                 URL: https://issues.apache.org/jira/browse/HDFS-12686
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 3.0.0-beta1
            Reporter: SammiChen
            Assignee: SammiChen


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.
