Joel Koshy updated KAFKA-429:
-----------------------------
Attachment: KAFKA-429-trunk-v1.patch
KAFKA-429-0.8-v1.patch
Patch for 0.8 and trunk.
This adds a new log4j controller mbean that allows getting/setting log4j levels
dynamically.
The logging trait forces initialization of the companion object. This means
tools such as console consumer and mirror maker get the mbean automatically
(since most of the tools use the logging trait).
Also, I removed the older LoggerDynamicMbean which is superseded by the new
mbean.
Finally (unrelated): log the throwable on producer send exception.
> Expose JMX operation to set logger level dynamically

> With KAFKA-16, we can change logger levels dynamically, but that is a global
> setting - i.e., it affects logging in all classes. It would be useful to
> expose a setLoggerLevel/add appenders operation that can be applied to
> classes/packages.
> We should also add this for the tools (and not just the broker) - e.g.,
> mirror-maker, console consumer, etc.
