Ashish Singhi commented on HBASE-12630:
---------------------------------------
Introduced a new configuration
{{"hbase.configuration.observer.max.exception.retries"}} with default value of
10.
If a observer throws exception *continuously* for 10 times(default) or user
configured value while updating its configuration then it will deregister the
observer.
Attached patch is for trunk branch.
Please review and share your comments.
Thanks

> Chatting with Manukranth, online config update feature should handle the case
> where certain ConfigurationObserver(s) constantly produce exception when
> notified of config update.
> We can handle such ConfigurationObserver by sidelining it after configurable
> number of exceptions seen from the ConfigurationObserver.
