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

             Summary: DataXceiver#copyBlock should return if block is pinned
                 Key: HDFS-9713
                 URL: https://issues.apache.org/jira/browse/HDFS-9713
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
    Affects Versions: 2.7.2
            Reporter: Uma Maheswara Rao G
            Assignee: Uma Maheswara Rao G


in DataXceiver#copyBlock
{code}
  if (datanode.data.getPinning(block)) {
      String msg = "Not able to copy block " + block.getBlockId() + " " +
          "to " + peer.getRemoteAddressString() + " because it's pinned ";
      LOG.info(msg);
      sendResponse(ERROR, msg);
    }
{code}
I think we should return back instead of proceeding to send block.as we already 
sent ERROR here.
