Description

The idea of this jira is to provide batch API in DistributedFileSystem to list the ECZoneInfo.

API signature:-

  /**
  * List all ErasureCoding zones. Incrementally fetches results from the server.
  */
  public RemoteIterator<ECZoneInfo> listErasureCodingZones() throws IOException {
    return dfs.listErasureCodingZones();
  }
