Jesse Yates updated HBASE-7047:
-------------------------------
Attachment: hbase-7047-v0-adv.patch
Attaching 'advanced' version of v0 that does some more advanced refactoring of
the offline snapshot handler to take advantage of the new framework.
Specifically, uses a centralized notification 'hub' to track the running
handler and then uses the added StopNotification to pass a 'stop' update to the
running DisabledTableSnapshotHandler. This is really nice in that it is
basically zero overhead to running multiple snapshots or adapting for stopping
a running snapshot and any restores.

>
> The current error handling framework introduced in HBASE-6571 adds a lot of
> complexity for what is essentially a solved problem. Specifically,
> cross-thread notifications have been generalized for the JMX tooling in the
> javax.management classes.
> Similar to what we developed, they have a NotifciationBroadcaster,
> NotificationListener, etc. though these are interfaces rather than general
> classes. These javax classes can be used almost 1-to-1 as replacements for
> things like the ExceptionOrchestrator and ExceptionListener. This also gives
> us the opportunity to easily add primitive notifications for standard HBase
> things like (1) timeouts, (2) aborts, and (3) server stops since the
> framework already considers things like typed notifications.
