tianjuan created YARN-9012: ------------------------------ Summary: NPE in scheduler UI when min-capacity is not configured Key: YARN-9012 URL: https://issues.apache.org/jira/browse/YARN-9012 Project: Hadoop YARN Issue Type: Bug Affects Versions: 3.1.1 Reporter: tianjuan Fix For: 3.1.1
I encountered the following while reviewing and testing branch YARN-5881. The design document from YARN-5881 says that for max-capacity: {quote} For any queue: If min-resource not set, it is automatically set to 0. (Same as today) {quote} When I try leaving blank {{yarn.scheduler.capacity.< queue-path>.capacity}}, the RMUI scheduler page refuses to render. It looks like it's in {{CapacitySchedulerPage$ LeafQueueInfoBlock}}: {noformat} at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.NullPointerException at org.apache.hadoop.yarn.server.resourcemanager.webapp.CapacitySchedulerPage$LeafQueueInfoBlock.renderQueueCapacityInfo(CapacitySchedulerPage.java:163) at org.apache.hadoop.yarn.server.resourcemanager.webapp.CapacitySchedulerPage$LeafQueueInfoBlock.renderLeafQueueInfoWithPartition(CapacitySchedulerPage.java:108) at org.apache.hadoop.yarn.server.resourcemanager.webapp.CapacitySchedulerPage$LeafQueueInfoBlock.render(CapacitySchedulerPage.java:97) at org.apache.hadoop.yarn.webapp.view.HtmlBlock.render(HtmlBlock.java:69) at org.apache.hadoop.yarn.webapp.view.HtmlBlock.renderPartial(HtmlBlock.java:79) at org.apache.hadoop.yarn.webapp.View.render(View.java:243) at org.apache.hadoop.yarn.webapp.view.HtmlBlock$Block.subView(HtmlBlock.java:43) at org.apache.hadoop.yarn.webapp.hamlet2.HamletImpl$EImp._v(HamletImpl.java:117) at org.apache.hadoop.yarn.webapp.hamlet2.Hamlet$LI.__(Hamlet.java:7709) at org.apache.hadoop.yarn.server.resourcemanager.webapp.CapacitySchedulerPage$QueueBlock.render(CapacitySchedulerPage.java:342){noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
