Haibo Chen commented on YARN-6218: ---------------------------------- Thanks for the patch [~miklos.szeg...@cloudera.com]! Took a cursory look at the patch. 1) In places where sleep() is replaced with waitForNMHeartbeat(), we may want to update the comments as well since " sleep to let NM's heartbeat to RM and trigger allocations" no longer makes sense. 2) At line 1015, the code is check container status from NMs, so it does not need to wait for NM heartbeats to RM. 3) bq. // Wait for fair scheduler update thread We are synchronously calling update() in the test thread, not waiting for the update thread. so maybe we can say triggering fair scheduler update? > TestAMRMClient fails with fair scheduler > ---------------------------------------- > > Key: YARN-6218 > URL: https://issues.apache.org/jira/browse/YARN-6218 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Miklos Szegedi > Assignee: Miklos Szegedi > Priority: Minor > Attachments: YARN-6218.000.patch > > > We ran into this issue on v2.
