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。

 

 

　　这就是，若指定删除的列，则

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

　　只删除，被指定的列
