bq. For other built-in EC policies, they are disabled by default.
This isn't from your change, but we should fix. Out of all the EC policies, 
RS(6,3) is enabled by default.

+1 pending, thanks for the work.

Thanks [~xiaochen] for the suggestion.

Have updated the documentation on this as suggested by you.So as to reduce any 
confusion that replication is not any kind of EC policy to users.

Pls Review!!!

Thanks for reporting the issue and the discussion [~SouryakantaDwivedy] and 
[~ayushtkn].

I agree this would be confusing to users - we can update the description and 
documentation around this.

 

Unfortunately, for compatibility reasons, we cannot change the getPolicy output 
(e.g. is unspecified). The message is deliberately printed from 
[here|https://github.com/apache/hadoop/blob/branch-3.0.0/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/tools/ECAdmin.java#L238-L243]

Souryakanta Dwivedy commented on HDFS-13774:


But as per the " -setPolicy" description for "HDFS Erasure Coding" it is 
specified in as  

{{"-replicate}} apply the special {{REPLICATION}} policy on the directory, 
force the directory to adopt 3x replication scheme."

which is quite confusing as what is special REPLICATION policy. It needs to be 
modified as if we set policy as -replicate then the 

directory take the default Replication policy instead of any defined EC policy.

Thanks [~SouryakantaDwivedy] for putting up the issue.

The reason for not returning the name of policy is that "Replication" is not an 
EC policy. It just acts like a flag to make the directory take the default 
Replication policy instead of an EC policy defined on its parent.

Even if you use the ec -listPolicies command you won't see replication there.

>  Erasure coding: "hdfs ec -getPolicy"" is not retrieving policy details when 
> the special REPLICATION policy set on the directory
> Steps :-
>  - Create a directory "testEC"
> - Get the EC policy for the directory [Received message as : "The erasure 
> coding policy of /testEC is unspecified" ]
> - Enable any Erasure coding policy like "XOR-2-1-1024k"
> - Set the EC Policy on the Directory
> - Get the EC policy for the directory [Received message as : "XOR-2-1-1024k" ]
> - Now again set the EC Policy on the directory as "replicate" special 
> REPLICATION policy
> - Get the EC policy for the directory [Received message as : "The erasure 
> coding policy of /testEC is unspecified" ]
>  The policy is being set for the Directory ,but while retrieving policy 
> details its throwing error as 
>  policy for the directory is unspecified which is wrong behavior
