Nathan Roberts commented on YARN-6768: -------------------------------------- Thanks Jon! As a datapoint, I have a testcase that measures how quickly we can handle NodeUpdateSchedulerEvents when a user is at their user limit. This path causes the ActivitiesLogger to be invoked at a very high rate. The most expensive operation within the ActivitiesLogger is application.getApplicationId().toString(). When I apply the patch on this jira, the throughput improves from 22K/sec to 32K/sec. > Improve performance of yarn api record toString and fromString > -------------------------------------------------------------- > > Key: YARN-6768 > URL: https://issues.apache.org/jira/browse/YARN-6768 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Jonathan Eagles > Assignee: Jonathan Eagles > Attachments: YARN-6768.1.patch, YARN-6768.2.patch > > -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
