Jonathan Hsieh commented on HBASE-7290:
---------------------------------------
For now I'm going to focus on the simple flush hfile only snapshot. Log-based
snapshots (simple log, and global consistent) actually has non-trivial problems
when: 1) a snapshot is taken, 2) edits occur, 3) a restore happens and 4) a
crash causes recovery to be triggered. This seems to allow writes from the
period after the snapshot and before the restore to be recovered in a crash
scenario.

> HBASE-6055 will be closed when the offline snapshots pieces get merged with
> trunk. This umbrella issue has all the online snapshot specific patches.
> This will get merged once one of the implementations makes it into trunk.
> Other flavors of online snapshots can then be done as normal patches instead
> of on a development branch.
