Hi,
Following code is I got used to create table with index.
Now, I think it's no need for us to keep multiple version of data.
How can I set my hbase table only to keep one version of data?
Better to give me some codes that I can add to my following function.
Thanks
public void createTableWithIdx(String tablename,String
columnfamily,String idx_columnfamily,String idx_column) throws IOException
{
HTableDescriptor desc = new HTableDescriptor(tablename);
String[] temp;
String delimiter = ",";
temp = columnfamily.split(delimiter);
for(int i =0; i < temp.length ; i++){
desc.addFamily(new HColumnDescriptor(temp[i]));
}
IndexedTableDescriptor idx_desc = new IndexedTableDescriptor(desc);
idx_desc.addIndex(new IndexSpecification(idx_column,
Bytes.toBytes(idx_columnfamily+":"+idx_column)));
IndexedTableAdmin admin = null;
admin = new IndexedTableAdmin(config);
admin.createIndexedTable(idx_desc);
System.out.println(tablename+" "+" create table and index
successfully");
}
