Ahmed Radwan created YARN-140: --------------------------------- Summary: 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 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.
