Sandy Ryza updated YARN-1228: ----------------------------- Summary: Clean up Fair Scheduler configuration loading (was: Don't allow other file than fair-scheduler.xml to be Fair Scheduler allocations file) > Clean up Fair Scheduler configuration loading > --------------------------------------------- > > 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.
