HBase编程 API入门系列之delete（客户端而言）（3）

　　心得，写在前面的话，也许，中间会要多次执行，连接超时，多试试就好了。

　　前面的基础，如下

HBase编程 API入门系列之put（客户端而言）（1）

HBase编程 API入门系列之get（客户端而言）（2）

hbase(main):001:0> scan 'test_table2'
ROW COLUMN+CELL
row_04 column=f1:name, timestamp=1478117286377, value=Andy3
row_04 column=f2:name, timestamp=1478117286377, value=Andy3
1 row(s) in 1.5670 seconds

hbase(main):002:0>

　　如现在这样，不指定，默认把所有的列全会删除（开发实际中，一定要加指定呀）

　　这就是，若不指定删除的列，则

Delete delete = new Delete(Bytes.toBytes("row_2"));

　　会删除，全部的列。

delete.deleteColumn(Bytes.toBytes("f1"), Bytes.toBytes("email"));
delete.deleteColumn(Bytes.toBytes("f1"), Bytes.toBytes("name"));

　　只删除，被指定的列
