Wilfred Spiegelenburg commented on YARN-10124: ---------------------------------------------- 1: this point by itself sounds good, we want the child queues to get resources and run the apps until they finish 2: if when 0 is set for the parent it is always above the hard limit then how does 1 work? I would have expected that the limit is enforced in the hierarchy. So can you please explain a bit more on how this works as this is not what I would expect. 2: (second time) any resource above the limit should be preemptable so it lines up with the first point 2. 3: is expected I would consider setting any on the root (min max etc) as a bug: the root is the whole cluster and shoulkd thus mirror what is available in the cluster without limits. Otherwise a cluster could never grow or shrink. > Remove restriction of ParentQueue capacity zero when childCapacities > 0 > ------------------------------------------------------------------------ > > Key: YARN-10124 > URL: https://issues.apache.org/jira/browse/YARN-10124 > Project: Hadoop YARN > Issue Type: Bug > Components: capacity scheduler > Affects Versions: 3.3.0 > Reporter: Prabhu Joseph > Assignee: Prabhu Joseph > Priority: Major > Attachments: YARN-10124-001.patch > > > ParentQueue capacity cannot be set to 0 when child capacities > 0.
