> Starting on 0.96.0.  HColumnDescriptor.DEFAULT_VERSIONS change to 1 from 3. So a columnfamily
will be default have 1 version of data. Currently a user can specifiy the maxVersion during
create table time or alter the columnfam later. This feature will add a configuration point
in hbase-sit.xml so that an admin can set the default globally. 
> a small discussion in [HBASE-10941|https://issues.apache.org/jira/browse/HBASE-10941]
