> Currently the hlog zk node is added before creating the log file, so it's possible to raise FileNotFoundException if the server crash between these tow operations. Move this step after file creating can avoid this exception (then FNFE will be certainly treated as an error). If there is an crash after log creation before creating the zk node, the log will be replayed and there should be no data loss either.
