Subject RE: about using HBase?
Date Thu, 17 Jan 2008 08:05:37 GMT

See the HBaseAdmin and HTable, HConnection classes.
If you use a eclipse for develop, i'd recommend the Outline Viewer.

Or, you can also use the HQL as describe below.

HQLClient hql = new HQLClient(new HBaseConfiguration(), MASTER_ADDRESS, null, null);
ReturnMsg rs = hql.executeQuery("create table webtable('content','title');");


B. Regards,

Edward yoon @ NHN, corp.
