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)
