> Since the block size of recovered edits and hlog are the same right now, if
> we set a large value to block size, name node may not able to assign enough
> space when we do log splitting. But set a large value to hlog block size can
> help reduce the number of region server asking for a new block. Thus I think
> separate the config of block size is necessary.
