Eric Payne created YARN-7575: -------------------------------- Summary: When using absolute capacity configuration with no max capacity, scheduler UI NPEs and can't grow queue Key: YARN-7575 URL: https://issues.apache.org/jira/browse/YARN-7575 Project: Hadoop YARN Issue Type: Bug Components: capacity scheduler Reporter: Eric Payne
I encountered the following while reviewing and testing branch YARN-5881. The design document from YARN-5881 says that for max-capacity: {quote} 3) For each queue, we require: a) if max-resource not set, it automatically set to parent.max-resource {quote} When I try leaving blank {{yarn.scheduler.capacity.< queue-path>.maximum-capacity}}, the RMUI scheduler page refuses to render. It looks like it's in {{CapacitySchedulerPage$ LeafQueueInfoBlock}}: {noformat} 2017-11-28 11:29:16,974 [qtp43473566-220] ERROR webapp.Dispatcher: error handling URI: /cluster/scheduler java.lang.reflect.InvocationTargetException ... at org.apache.hadoop.yarn.server.resourcemanager.webapp.CapacitySchedulerPage$LeafQueueInfoBlock.renderQueueCapacityInfo(CapacitySchedulerPage.java:164) at org.apache.hadoop.yarn.server.resourcemanager.webapp.CapacitySchedulerPage$LeafQueueInfoBlock.renderLeafQueueInfoWithoutParition(CapacitySchedulerPage.java:129) {noformat} Also... A job will run in the leaf queue with no max capacity set and it will grow to the max capacity of the cluster, but if I add resources to the node, the job won't grow any more even though it has pending resources. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
