Subject [jira] [Updated] (HBASE-8176) Backport HBASE-5335 "Dynamic Schema Configurations"
Date Fri, 29 Mar 2013 14:54:13 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8176?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Purtell updated HBASE-8176:
----------------------------------

    Release Note: 
With HBASE-8176("Dynamic Schema Configurations"), we can define table/column family specific
configuration by HColumnDescriptor.setValue() or HTableDescriptor.setValue(). We can also
do this easily in hbase shell.

Change the table-scope by set attribute CONFIG like this:
alter 'test', METHOD => 'table_att', CONFIG => {'hbase.hstore.compaction.min' =>
'5'}

Change the column family config by set attribute CONFIG like this: 
alter 'test',  NAME => 'f', CONFIG => {'hbase.hstore.compaction.min' => a'5'}

Copied release note to issue.
