> This is because when [deserializing protobuf|https://github.com/apache/hadoop/blob/branch-3.0.0-beta1/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/protocolPB/PBHelperClient.java#L2942],
the static instance of [SystemErasureCodingPolicies class|https://github.com/apache/hadoop/blob/branch-3.0.0-beta1/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/protocol/SystemErasureCodingPolicies.java#L101]
is first checked, and always returns the cached policy objects, which are created by default
with state=DISABLED.
> All the existing unit tests pass, because that static instance that the client (e.g.
ECAdmin) reads in unit test is updated by NN. :)
