[jira] [Created] (HBASE-10950) Add a configuration point for MaxVersion of Column Family

Demai Ni created HBASE-10950:
--------------------------------

             Summary: Add  a configuration point for MaxVersion of Column Family
                 Key: HBASE-10950
                 URL: https://issues.apache.org/jira/browse/HBASE-10950
             Project: HBase
          Issue Type: Improvement
          Components: Admin
    Affects Versions: 0.96.0, 0.98.0
            Reporter: Demai Ni
            Assignee: Demai Ni
             Fix For: 0.99.0, 0.98.2, 0.96.3


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] lead to this jira
