You mean change the order here boss?


  @Override
  public void sync() throws IOException {
    if (this.syncFs != null) {
      try {
       this.syncFs.invoke(this.writer, HLog.NO_ARGS);
      } catch (Exception e) {
        throw new IOException("Reflection", e);
      }
    } else if (this.hflush != null) {
      try {
        this.hflush.invoke(getWriterFSDataOutputStream(), HLog.NO_ARGS);
      } catch (Exception e) {
        throw new IOException("Reflection", e);
      }
    }
  }


Call hflush if its available ahead of syncFs?

Seems like we should get this in all around.  I can do it.

Good stuff,
