yarn.scheduler.capacity.maximum-applications 10000 Maximum number of applications that can be pending and running. yarn.scheduler.capacity.maximum-am-resource-percent 0.1 Maximum percent of resources in the cluster which can be used to run application masters i.e. controls number of concurrent running applications. yarn.scheduler.capacity.resource-calculator org.apache.hadoop.yarn.util.resource.DefaultResourceCalculator The ResourceCalculator implementation to be used to compare Resources in the scheduler. The default i.e. DefaultResourceCalculator only uses Memory while DominantResourceCalculator uses dominant-resource to compare multi-dimensional resources such as Memory, CPU etc. yarn.scheduler.capacity.root.queues default The queues at the this level (root is the root queue). yarn.scheduler.capacity.root.default.capacity 100 Default queue target capacity. yarn.scheduler.capacity.root.default.user-limit-factor 1 Default queue user limit a percentage from 0.0 to 1.0. yarn.scheduler.capacity.root.default.maximum-capacity 100 The maximum capacity of the default queue. yarn.scheduler.capacity.root.default.state RUNNING The state of the default queue. State can be one of RUNNING or STOPPED. yarn.scheduler.capacity.root.default.acl_submit_applications * The ACL of who can submit jobs to the default queue. yarn.scheduler.capacity.root.default.acl_administer_queue * The ACL of who can administer jobs on the default queue. yarn.scheduler.capacity.node-locality-delay -1 Number of missed scheduling opportunities after which the CapacityScheduler attempts to schedule rack-local containers. Typically this should be set to number of racks in the cluster, this feature is disabled by default, set to -1.
