> In HA setup, the JNs receive edit logs (blob) from the NN and write into edit
> log files. In order to write well-formed edit log files, the JNs prepend a
> header for each edit log file.
> The problem is that the JN hard-codes the version (i.e.,
> {{NameNodeLayoutVersion}} in the edit log, therefore it generates incorrect
> edit logs when the newer release bumps the {{NameNodeLayoutVersion}} during
> rolling upgrade.
