Subject [jira] [Updated] (HBASE-10950) Add a configuration point for MaxVersion of Column Family
Date Wed, 16 Apr 2014 22:00:19 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10950?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Enoch Hsu updated HBASE-10950:
------------------------------

    Status: Patch Available  (was: Open)

Added patch to fix and a UT to test the change.
UT was added to hbase-server because of usage of HBaseTestingUtility.
If I add the UT to hbase-client then it creates a circular dependency on hbase-server

> 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]
