Junping Du updated MAPREDUCE-4309: ---------------------------------- Attachment: MAPREDUCE-4309.patch > Make locatlity in YARN's container assignment and task scheduling pluggable > for other deployment topology > --------------------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-4309 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4309 > Project: Hadoop Map/Reduce > Issue Type: Bug > Affects Versions: 1.0.0, 2.0.0-alpha > Reporter: Junping Du > Assignee: Junping Du > Attachments: > HADOOP-8474-ContainerAssignmentTaskScheduling-pluggable.patch, > MAPREDUCE-4309.patch > > > There are several classes in YARN’s container assignment and task scheduling > algorithms that relate to data locality which were updated to give preference > to running a container on other locality besides node-local and rack-local > (like nodegroup-local). This propose to make these data structure/algorithms > pluggable, like: SchedulerNode, RMNodeImpl, etc. The inner class > ScheduledRequests was made a package level class to it would be easier to > create a subclass, ScheduledRequestsWithNodeGroup. -- This message is automatically generated by JIRA.
