Description

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).

This is the complete stack trace of a blocked thread on timeline server:-
