Description

This is a clone bug of HDFS-11644 to provide a quick fix while a proper fix is being discussed and developed. The quick fix here would be to just turn DFSStripedOutputStream#hsync()/hflush() as a no-op instead of throwing UnsupportedOperationException.

  @Override
  public void hflush() {
    throw new UnsupportedOperationException();
  }

  @Override
  public void hsync() {
    throw new UnsupportedOperationException();
  }

For more details please refer to the comments in HDFS-11644.
