totally forgot abt it now..  [~ashish singhi] on vacation right now and once he 
is back, he can comment abt the discussion points happened at that time.

>          Issue Type: Bug
>            Reporter: Ted Yu
>
> Currently the support for replication of bulk loaded hfiles relies on bulk 
> load marker written in the WAL.
> The move of bulk loaded hfile(s) (into region directory) may succeed but the 
> write of bulk load marker may fail.
> This means that although bulk loaded hfile is being served in source cluster, 
> the replication wouldn't happen.
> Normally operator is supposed to retry the bulk load. But relying on human 
> retry is not robust solution.
