1.Eclipse中运行JAVA代码远程操作HBase的示例

2. Windows下安装HBase

3. Java 下 select Hbase 各级元素 code sample

public void listAll(HTable table,String family) throws IOException {try {//1.table->(family->Result row)->(row.getFamilyMap->Entry)->(column(key),value)for(Result row: table.getScanner(family.getBytes())){System.out.format("ROW\t%s\n",new String(row.getRow()));for(Map.Entry<byte[],byte[]> entry : row.getFamilyMap(family.getBytes()).entrySet()){String column = new String(entry.getKey());String value =  new String(entry.getValue());System.out.format("column\tfamily:%s\t%s\n",column,value );}}//2. table->Result row->(row.raw()->KeyValue)->(row,family,timestamp,qualifier(column),value)                                Scan scan = new Scan();//for(Result row: table.getScanner(scan){//for(KeyValue kv: row.raw()){//kv.getRow()//kv.getFamily()//kv.getTimestamp()//kv.getQualifier()//kv.getValue()//}//}//3.table->(family->Result row)->(row.getColumn->KeyValue)->(row,family,timestamp,value)for(Result row: table.getScanner(family.getBytes())){for(KeyValue kv: row.getColumn(family.getBytes(), "age".getBytes()) ){System.out.format("%s\t%s\t%s\t%s\t%s\n", new String(kv.getRow()),new String(kv.getFamily()),kv.getTimestamp(),kv.getType(),new String(kv.getValue()));}}} catch (IOException e) {DBHelper.getAdmin().close();throw e;}}

4. 建二级索引表

original：

id -> row->family->column->value

now:

value->id id -> row->family->column->value
