habse的CopyTable

需求：对hbase的一张表进行拷贝

一、table1的内容如下

hbase(main)::> scan 'table1'
ROW                                              COLUMN+CELL
                                                column=f1:age, timestamp=, value=
                                                column=f1:gender, timestamp=, value=male
                                                column=f1:name, timestamp=, value=zhangsan
                                                column=f1:name, timestamp=, value=lisi
                                                column=f1:name, timestamp=, value=wangwu
                                                column=f1:birthday, timestamp=, value=
                                                column=f1:name, timestamp=, value=zhaoliu
 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)::> scan 'table2'
ROW                                              COLUMN+CELL
                                                column=f1:age, timestamp=, value=
                                                column=f1:gender, timestamp=, value=male
                                                column=f1:name, timestamp=, value=zhangsan
                                                column=f1:name, timestamp=, value=lisi
                                                column=f1:name, timestamp=, value=wangwu
                                                column=f1:birthday, timestamp=, value=
                                                column=f1:name, timestamp=, value=zhaoliu
 row(s) in 0.0260 seconds
