Jesse Yates updated HBASE-7047:
-------------------------------
Attachment: java_6667-v0.txt
Attaching simple version that refactors the error handling (removing excess
classes/tests). This patch also modifies the current implementation of the
offline snapshots (HBASE-6863) to use the new classes - slight tweaks, but
nothing too crazy.
> [snapshots] Refactor error handling to use javax.management

>
> 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.
