需求：对hbase的一张表进行拷贝
一、table1的内容如下
hbase(main):018:0> scan ‘table1‘ ROW COLUMN+CELL 1 column=f1:age, timestamp=1469069255119, value=10 1 column=f1:gender, timestamp=1469069255119, value=male 1 column=f1:name, timestamp=1469069255119, value=zhangsan 2 column=f1:name, timestamp=1469069255119, value=lisi 3 column=f1:name, timestamp=1469069255119, value=wangwu 4 column=f1:birthday, timestamp=1469069255119, value=1993 4 column=f1:name, timestamp=1469069255119, value=zhaoliu 4 row(s) in 0.0300 seconds
二、现在将table1拷贝
hbase org.apache.hadoop.hbase.mapreduce.CopyTable --new.name=table2 table1
三、scan table2中的数据
hbase(main):026:0> scan ‘table2‘ ROW COLUMN+CELL 1 column=f1:age, timestamp=1469069255119, value=10 1 column=f1:gender, timestamp=1469069255119, value=male 1 column=f1:name, timestamp=1469069255119, value=zhangsan 2 column=f1:name, timestamp=1469069255119, value=lisi 3 column=f1:name, timestamp=1469069255119, value=wangwu 4 column=f1:birthday, timestamp=1469069255119, value=1993 4 column=f1:name, timestamp=1469069255119, value=zhaoliu 4 row(s) in 0.0260 seconds
