Junping Du commented on YARN-18: -------------------------------- Thanks Luke for your review and comments! I addressed almost all your points in V4 patch except for putting ScheduledRequests in topology related factory class for YARN as I think this is the object created within MRAppMaster but not YARN ResourceManager like other objects so in different package. Am I missing something? > 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, YARN-18-v4.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.
