[jira] [Commented] (YARN-7266) Timeline Server event handler
threads locked
[ https://issues.apache.org/jira/browse/YARN-7266?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16771982#comment-16771982 ]
Prabhu Joseph commented on YARN-7266:
-------------------------------------
The http threads in problematic jstack creates a new {{JAXBContextImpl}} everytime while accepting the http request which causes the synchronization issue.
Have below two ways to explore:
1. Implement a custom Jaxb context factory (javax.xml.bind.context.factory) which reuses the {{JAXBContextImpl}}. The default {{ContextFactory}} creates a new {{JAXBContextImpl}} every time.
2. Check if Jersey has a way to reuse {{JAXBContextImpl}} / Jersey {{JSONJAXBContext}} while accepting http request in similar to what it does when writing response through {{ContextResolver}} ({{JAXBContextResolver}} / {{YarnJacksonJaxbJsonProvider}})
Issue is applicable for other Webservices like RM, AM. This affects ATSV2 Timeline Reader WebService.

> 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).
