Prabhu Joseph commented on YARN-10139: -------------------------------------- Thanks [~adam.antal] for reviewing. Have included a testcase in [^YARN-10139-002.patch] . > ValidateAndGetSchedulerConfiguration API fails when cluster max allocation > > default 8GB > ---------------------------------------------------------------------------------------- > > Key: YARN-10139 > URL: https://issues.apache.org/jira/browse/YARN-10139 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 3.3.0 > Reporter: Prabhu Joseph > Assignee: Prabhu Joseph > Priority: Major > Attachments: YARN-10139-001.patch, YARN-10139-002.patch > > > ValidateAndGetSchedulerConfiguration fails when the cluster max allocation > (yarn.scheduler.maximum-allocation-mb) is set to resource (eg: 16GB) > > default 8GB in yarn-site.xml. > As part of validation API, there are two configuration used - > CapacitySchedulerConfiguration and Configuration (yarn-site.xml). When > CapacityScheduler is initialized with CapacitySchedulerConfiguration, as part > of queues initialization, it checks the queue maximum allocation which is not > present and so checks cluster max allocation which is not present (it is > present only in YarnConfiguration) and defaults to 8GB. This will fail as > queue max allocation 8GB is decreased from previous 16GB. > {code} > 2020-02-14 07:38:46,087 WARN > org.apache.hadoop.yarn.server.resourcemanager.webapp.RMWebServices: > CapacityScheduler configuration validation failed:java.io.IOException: Failed > to re-init queues : Trying to reinitialize root.default.c1.c3 the maximum > allocation size can not be decreased!
