----------------------------------
Can we close this as duplicate in favor of HBASE-11780?
> Allow load balancer to accommodate different region server configurations
> -------------------------------------------------------------------------
>
> Key: HBASE-7297
> URL: https://issues.apache.org/jira/browse/HBASE-7297
> Project: HBase
> Issue Type: New Feature
> Components: Balancer
> Reporter: Ted Yu
> Priority: Major
>
> Robert Dyer raised the following scenario under the thread of 'Multiple
> regionservers on a single node':
> {quote}
> I have a very small cluster where all nodes are identical. However, I was
> just given a very powerful node to add into this cluster which effectively
> doubles the total CPUs, RAM, and HDDs in the cluster.
> As such, when I run a MR job half the jobs go to this single, new node yet
> most of the data is not local due to HBase balancing the regions.
> {quote}
> Load balancer should take region server config (total heap in the above case)
> into account when allocating regions.
