@Override
public void shipped() throws IOException {
  if (prevCell != null) {
    // Do the copy here so that in case the prevCell ref is pointing to the previous
    // blocks we can safely release those blocks.
    // This applies to blocks that are got from Bucket cache, L1 cache and the blocks
    // fetched from HDFS. Copying this would ensure that we let go the references to these
    // blocks so that they can be GCed safely(in case of bucket cache)
    prevCell = KeyValueUtil.toNewKeyCell(this.prevCell);
  }
  matcher.beforeShipped();
  // There wont be further fetch of Cells from these scanners. Just close.
  clearAndClose(scannersForDelayedClose);
  if (this.heap != null) {
    this.heap.shipped();
    // When switching from pread to stream, we will open a new scanner for each store file, but
    // the old scanner may still track the HFileBlocks we have scanned but not sent back to client
    // yet. If we close the scanner immediately then the HFileBlocks may be messed up by others
    // before we serialize and send it back to client. The HFileBlocks will be released in shipped
    // method, so we here will also open new scanners and close old scanners in shipped method.
    // See HBASE-18055 for more details.
