Now YARN service doesn't allow specifying service name equals to component name. And it causes AM launch fails with msg like: {code} org.apache.hadoop.metrics2.MetricsException: Metrics source tf-zeppelin already exists! at org.apache.hadoop.metrics2.lib.DefaultMetricsSystem.newSourceName(DefaultMetricsSystem.java:152) at org.apache.hadoop.metrics2.lib.DefaultMetricsSystem.sourceName(DefaultMetricsSystem.java:125) at org.apache.hadoop.metrics2.impl.MetricsSystemImpl.register(MetricsSystemImpl.java:229) at org.apache.hadoop.yarn.service.ServiceMetrics.register(ServiceMetrics.java:75) at org.apache.hadoop.yarn.service.component.Component.<init>(Component.java:193) at org.apache.hadoop.yarn.service.ServiceScheduler.createAllComponents(ServiceScheduler.java:552) at org.apache.hadoop.yarn.service.ServiceScheduler.buildInstance(ServiceScheduler.java:251) at org.apache.hadoop.yarn.service.ServiceScheduler.serviceInit(ServiceScheduler.java:283) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:164) at org.apache.hadoop.service.CompositeService.serviceInit(CompositeService.java:108) at org.apache.hadoop.yarn.service.ServiceMaster.serviceInit(ServiceMaster.java:142) at org.apache.hadoop.service.AbstractService.init(AbstractService.java:164) at org.apache.hadoop.yarn.service.ServiceMaster.main(ServiceMaster.java:338) 2018-06-18 06:50:39,473 [main] INFO service.ServiceScheduler - Stopping service scheduler {code} It's better to add this check in validation phase instead of failing AM. -- 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
