Hi Ramkrishna,
I think relocating regions is based on the queries and queried data.
The relocation can scatter the regions involved

Thanks for your response. I answered your questions inline in Blue.
And I'd like to give an example to describe my problem.

I have a table with a hundred or so regions. When I look in the hbase
web ui, I see that all the regions are on one server. Of course we have
many other tables and lots of data. Some tables

The assumption was that regions were not evenly distributed prior to
restarting.
If they were, user wouldn't select this policy.
We can this policy effective only once - retain assignment is selected
following this new policy.
Of course the dynamic portion of load balancer needs to select the
to be distributed across many machines?
Just curious to understand the nuance. If I *do* want a uniform
distribution of regions to servers, how would I achieve it?

Hey Geoff:
Is this a 0.90.2 (or .3) hbase? It had some fixup done on the
balancer to make it a little more random.
Otherwise, yes, a table should be better spread about the cluster.
This has come

You're right. I was thinking there was an Hbase balancer tool for spreading
the table's regions around. From your response, sounds like the hbase
