Arun C Murthy commented on HADOOP-5884: --------------------------------------- Long term - we really should fix TestCapacityScheduler to not check strings and use relevant apis (even package-private ones). > Capacity scheduler should account high memory jobs as using more capacity of > the queue > -------------------------------------------------------------------------------------- > > Key: HADOOP-5884 > URL: https://issues.apache.org/jira/browse/HADOOP-5884 > Project: Hadoop Core > Issue Type: Bug > Components: contrib/capacity-sched > Reporter: Hemanth Yamijala > Assignee: Vinod K V > Attachments: HADOOP-5884-20090529.1.txt > > > Currently, when a high memory job is scheduled by the capacity scheduler, > each task scheduled counts only once in the capacity of the queue, though it > may actually be preventing other jobs from using spare slots on that node > because of its higher memory requirements. In order to be fair, the capacity > scheduler should proportionally (with respect to default memory) account high > memory jobs as using a larger capacity of the queue. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
