Devaraj Das commented on HBASE-8344:
------------------------------------
bq. When will the globalFavoredNodesAssignmentPlan not contain a list of
favored nodes for this region?
Actually, not all regions might have favored-nodes when they enter the method
(FavoredNodeLoadBalancer.roundRobinAssignment). For example if the table is
getting created with pre-split regions; the regions will have favored-nodes
when the FavoredNodeLoadBalancer.roundRobinAssignment returns. OTOH a region
could have favored-nodes when it enters the method - when we are trying to
handle failure of its currently assigned regionserver.
