Wei Yan updated YARN-1290: -------------------------- Attachment: YARN-1290.patch > Let continuous scheduling achieve more balanced task assignment > --------------------------------------------------------------- > > Key: YARN-1290 > URL: https://issues.apache.org/jira/browse/YARN-1290 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Wei Yan > Assignee: Wei Yan > Attachments: main.pdf, YARN-1290.patch > > > Currently, in continuous scheduling (YARN-1010), in each round, the thread > iterates over pre-ordered nodes and assigns tasks. This mechanism may > overload the first several nodes, while the latter nodes have no tasks. > We should sort all nodes according to available resource. In each round, > always assign tasks to nodes with larger capacity, which can balance the load > distribution among all nodes. -- This message was sent by Atlassian JIRA (v6.1#6144)
