--------------------------------

OK, thanks [~hitliuyi] for pointing out this. Since I have done some background

have not yet started:)

> The idea of this jira is to provide batch API in {{DistributedFileSystem}} to 
> list the {{ECZoneInfo}}.
> API signature:-
> {code}
>   /**
>   * List all ErasureCoding zones. Incrementally fetches results from the 
> server.
>   */
>   public RemoteIterator<ECZoneInfo> listErasureCodingZones() throws 
> IOException {
>     return dfs.listErasureCodingZones();
>   }
> {code}
