Have you looked at http://hbase.apache.org/book.html#rsgroup ?

It is in 1.4.x release.

Hbase and Database distribution

[Oussema BEN LAMINE]

Hello,
i am using hbase 1.1.2, i have 5 region servers already working on my
cluster.
i want to create a hbase table that will be on just two of those five
region servers.
in other words, i want to save new table data on just two servers, not all.
any help will be appreciated,
thanks

Coprocessor prePut

[Yang Zhang]

Hi

 I overrode coprocessor prePut() function to prevent normal put, and
try to put the same data  with different rowkey into the same table.

 The code is "context.getEnvironment().getRegion().put(newPut);" . This
will caused an exception when the context's region splited. There are so
less document about coprocessor, so I write to the mail list .The exception
is below.

org.apache.hadoop.hbase.NotServingRegionException:
GISdoop_GeoKey,\xE6\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01|\xCA\xAD,1516949621636.9628785cfce941207f5d21bdf1eb0f40.
