BUG-44387 | Changed the value of
yarn.timeline-service.generic-application-history.save-non-am-container-meta-info
to false. This config defines if YARN will save container meta-info in the application
history store. | |
BUG-44902 | From this maintenance release for new clusters the default value for yarn.timeline-service.state-store-class has changed from LevelDBTimelineStore to RollingLevelDBTimelineStore. This change has been made for scalability and performance reasons, specifically to improve the performance when records older than the ttl interval have to be deleted. One side effect of this change is the removal of the fromTs API. |
