stack commented on HBASE-12627:
-------------------------------
>From the above noted thread: "Even with the manifest feature, it is still
>inefficient to iterate over
every hfile in the archive and check with the namenode to see if there is a
new snapshot manifest that may reference that single hfile rather than
doing that check a single time for the list of all archived hfiles." -- Dave
Latham
> Add back snapshot batching facility from HBASE-11360 dropped by HBASE-11742

> HBASE-11742 dropped the batching facility from HBASE-11360. It is less
> necessary now we do manifests rather than file-per but on big clusters the
> batching will come in handy. This issue is about studying and porting over
> the HBASE-11360 batching.
> This issue comes of discussion up on dev list
> http://search-hadoop.com/m/DHED40jnXP Marked as component 'scaling'.
