Eric Yang commented on YARN-7266:
---------------------------------
[~Prabhu Joseph] echo what [~rohithsharma] said about the resource file
location. If position correctly, in
src/main/resources/org/apache/hadoop/yarn/api/records/timeline/jaxb.properties,
the final jar file will merge the jaxb.properties in the same location as the
class file. The findbug error that static synchronization applies to the
method instead of synchronizing in the body of the method to allow
multi-threaded application to work correctly, which applies to the problem that
this patch tries to address.

> Event handlers for Timeline Server seem to take a lock while parsing HTTP
> headers of the request. This is causing all other threads to wait and slowing
> down the overall performance of Timeline server. We have resourcemanager
> metrics enabled to send to timeline server. Because of the high load on
> ResourceManager, the metrics to be sent are getting backlogged and in turn
> increasing heap footprint of Resource Manager (due to pending metrics).
