[jira] [Commented] (YARN-5324) Stateless router policies implementation

["Carlo Curino (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-5324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15380912#comment-15380912 ] 

Carlo Curino commented on YARN-5324:
------------------------------------

This patch provides 3 simple implementation of {{RouterFederationPolicy}}:
 # A uniform random choice among active subclusters
 # A weighted random choice among active subclusters, where the weights in the policy determine likelihood of picking a cluster (and =0 means actively excluding a subcluster)
 # A ordered priority among active subclusters, where the weights in the policy determine the "cost" of picking a cluster. The policy always picks the subcluster with the lowest weight.

> These are policies at the Router that do not require maintaing state across choices (e.g., weighted random).
