Examples of org.apache.hadoop.dfs.DataNode$Packet

org.apache.hadoop.dfs.DataNode
a class to throttle the block transfers This class is thread safe. It can be shared by multiple threads. The parameter bandwidthPerSec specifies the total bandwidth shared by threads.

      Class<? extends Packet> packetClass = (Class<? extends Packet>) packets[packetId];
      if (packetClass == null) {
        return null;
      }
      Constructor<? extends Packet> c = packetClass.getConstructor(new Class[]{});
      Packet r = c.newInstance(blank);


      return newInstance(packetId, r);
    } catch (SecurityException e) {
      throw new RuntimeException(e);
    } catch (NoSuchMethodException e) {
