Steve Loughran updated MAPREDUCE-3995: -------------------------------------- Status: Open (was: Patch Available) patch off while the next stage goes in: # useful listener -one that logs. # test listener -one that caches event history and can be set to fail on a specific state event; put this in test/ . > Add support for static service lifecycle listeners . > ----------------------------------------------------- > > Key: MAPREDUCE-3995 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3995 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Components: mrv2 > Affects Versions: 0.23.1, 0.24.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Minor > Attachments: MAPREDUCE-3995.patch, MAPREDUCE-3995.patch > > > Add support to {{AbstractService}} that allow callers to register listeners > for all instances. The existing listener interface could be used. This allows > management tools to hook into the events. > The static listeners would be invoked for all state changes except creation > (base class shouldn't be handing out references to itself at this point). > These static events could all be async, pushed through a shared > {{ConcurrentLinkedQueue}}; failures logged at warn and the rest of the > listeners invoked. -- This message is automatically generated by JIRA.
