Eric Yang commented on YARN-7266:
---------------------------------
Guice is used for dependency injection here. It looks like Guice did not help
with Jersey initialization. How difficult would it be to use
HttpServer2.Builder to initialize Jersey instead of Guice for timeline server?
I think moving wadl generation away from the serving thread may provide more
performance gain.

> 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).
