Luke Lu commented on YARN-18: ----------------------------- Preliminary comments: # We should use net.topology.nodegroup.aware instead of net.topology.with.nodegroup for configuration to be consistent with branch-1 code. # We should probably use yarn.resourcemanager.topology.aware.factory.impl to specify factory class for topology aware objects. # The topologoy aware objects should include ScheduledRequests and AppSchedulingInfo, which are currently not managed by the factory. # Pluggable interface/class should be public with the InterfaceAudience.Private annotation. > Make locatlity in YARN's container assignment and task scheduling pluggable > for other deployment topology > --------------------------------------------------------------------------------------------------------- > > Key: YARN-18 > URL: https://issues.apache.org/jira/browse/YARN-18 > Project: Hadoop YARN > Issue Type: New Feature > Affects Versions: 2.0.3-alpha > Reporter: Junping Du > Assignee: Junping Du > Labels: features > Attachments: > HADOOP-8474-ContainerAssignmentTaskScheduling-pluggable.patch, > MAPREDUCE-4309.patch, MAPREDUCE-4309-v2.patch, MAPREDUCE-4309-v3.patch, > MAPREDUCE-4309-v4.patch, MAPREDUCE-4309-v5.patch, MAPREDUCE-4309-v6.patch, > MAPREDUCE-4309-v7.patch, YARN-18.patch, YARN-18-v2.patch, YARN-18-v3.1.patch, > YARN-18-v3.2.patch, YARN-18-v3.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.
