Sandy Ryza created YARN-1228: -------------------------------- Summary: Don't allow other file than fair-scheduler.xml to be Fair Scheduler allocations file Key: YARN-1228 URL: https://issues.apache.org/jira/browse/YARN-1228 Project: Hadoop YARN Issue Type: Improvement Components: scheduler Affects Versions: 2.1.1-beta Reporter: Sandy Ryza
Currently the Fair Scheduler is configured in two ways * An allocations file that has a different format than the standard Hadoop configuration file, which makes it easier to specify hierarchical objects like queues and their properties. * With properties like yarn.scheduler.fair.max.assign that are specified in the standard Hadoop configuration format. The standard and default way of configuring it is to use fair-scheduler.xml as the allocations file and to put the yarn.scheduler properties in yarn-site.xml. It is also possible to specify a different file as the allocations file, and to place the yarn.scheduler properties in fair-scheduler.xml, which will be interpreted as in the standard Hadoop configuration format. This flexibility is both confusing and unnecessary. There's no need to keep around the second way. -- This message is automatically generated by JIRA.
