I have split the patch into an 'svn mv' script and the rest of the patch. Thanks Tucu for helping me offline to troubleshoot the pom issues to get c-s.xml on the classpath of tests. > Add capacity-scheduler-default.xml to provide a default set of configurations for the capacity scheduler. > --------------------------------------------------------------------------------------------------------- > > Key: YARN-140 > URL: https://issues.apache.org/jira/browse/YARN-140 > Project: Hadoop YARN > Issue Type: Bug > Components: capacityscheduler > Reporter: Ahmed Radwan > Assignee: Ahmed Radwan > Attachments: YARN-140.patch, YARN-140_rev2.patch, YARN-140_rev3.patch, YARN-140_rev4.patch, YARN-140_rev5.patch, YARN-140_rev5_svn_mv.patch > > > When setting up the capacity scheduler users are faced with problems like: > {code} > FATAL org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Error starting ResourceManager > java.lang.IllegalArgumentException: Illegal capacity of -1 for queue root > {code} > Which basically arises from missing basic configurations, which in many cases, there is no need to explicitly provide, and a default configuration will be sufficient. For example, to address the error above, the user need to add a capacity of 100 to the root queue. > So, we need to add a capacity-scheduler-default.xml, this will be helpful to provide the basic set of default configurations required to run the capacity scheduler. The user can still override existing configurations or provide new ones in capacity-scheduler.xml. This is similar to *-default.xml vs *-site.xml for yarn, core, mapred, hdfs, etc. -- This message is automatically generated by JIRA.
