Ted Yu commented on HBASE-3373:
-------------------------------
In preparation for HBASE-3616, I think we need to enhance this method in
SplitTransaction:
{code}
HRegion createDaughterRegion(final HRegionInfo hri,
final FlushRequester flusher)
{code}
requestsCount is initially 0 for daughter regions which doesn't reflect the
fact that parent region has been heavily accessed.
Maybe we can assign half of requestsCount of parent region to each daughter
region ?
> Allow regions of specific table to be load-balanced

> Project: HBase
> Issue Type: Improvement
> Components: master
> Affects Versions: 0.20.6
> Reporter: Ted Yu
> Fix For: 0.92.0
>
> Attachments: HbaseBalancerTest2.java
>
>
> From our experience, cluster can be well balanced and yet, one table's
> regions may be badly concentrated on few region servers.
> For example, one table has 839 regions (380 regions at time of table
> creation) out of which 202 are on one server.
> It would be desirable for load balancer to distribute regions for specified
> tables evenly across the cluster. Each of such tables has number of regions
> many times the cluster size.
