Ted Yu created HBASE-7297:
-----------------------------
Summary: 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: Bug
Reporter: Ted Yu
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.
