Rakesh R commented on HDFS-12258:
---------------------------------

Thanks [~zhouwei] for the patch. Following are few comments, please take care.
# Typo: {{Diabled}} -> {{Disabled}}
{code}
/**
* EC policy state.
*/
enum ErasureCodingPolicyState {
  Diabled = 1;
{code}
# Please use captial letters.
{{ErasureCodingPolicyState#Disabled, #Enabled, #Removed}} ==> 
{{ErasureCodingPolicyState#DISABLED, #ENABLED, #REMOVED}}
# Please add annotation to enum state
{code}
@InterfaceAudience.Public
@InterfaceStability.Evolving
public enum ErasureCodingPolicyState
{code}
# {{ErasureCodingPolicyManager#addPolicy(ErasureCodingPolicy policy)}} function 
is not considering the state. What if user sets {{ErasureCodingPolicy#state}} 
and invoked {{dfs#addErasureCodingPolicies()}} API?

> ec -listPolicies should list all policies in system, no matter it's enabled 
> or disabled
