> Key: HBASE-25938
> URL: https://issues.apache.org/jira/browse/HBASE-25938
> Project: HBase
> Issue Type: Bug
> Components: Balancer, FavoredNodes
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.5.0, 2.4.4
>
>
> After we introduced FavoredNodesManager, we do not need to load this
> information every time when balancing, as all the updates to favored nodes
> will go to FavoredNodesManager and it can update its in memory state
> accordingly.
> The current SnapshotOfRegionAssignmentFromMeta.initialize is just a dummy one
> in FavoredNodeLoadBalancer, as we never use it in the method.
> It will introduce a full scan on hbase:meta so let's just remove it.
