------------------------------------------------------------------
{quote}What if the split is stopped in between. (WAL split RS died).. Also
there may be other systems seeing directly the files under CF (Like offline
compaction tool). How we can give a consistent view of the CF files to these
other systems.
{quote}
For the WAL replay, it replay edits and may flush many times if the memstore is
big. And if RS died before finishing replay, the other systems cannot get a
consistent view of the CF files, too? So I thought HBase doesn't have this
guarantee before.
