一.导入导出

1.导出到hdfs

# hbase org.apache.hadoop.hbase.mapreduce.Export test /backup/test

或采用以下写法

# hbase org.apache.hadoop.hbase.mapreduce.Export test hdfs://sht-sgmhadoopnn-01:9011/backup/test

输出log

[root@sht-sgmhadoopdn-02 exp]# hbase org.apache.hadoop.hbase.mapreduce.Export test hdfs://sht-sgmhadoopnn-01:9011/backup/test

2.查看备份文件

# hadoop fs -ls /backup/test
Found 3 items
-rw-r--r--   3 root supergroup          0 2019-04-21 17:46 /backup/test/_SUCCESS
drwxr-xr-x   - root supergroup          0 2019-04-21 17:45 /backup/test/_logs
-rw-r--r--   3 root supergroup        310 2019-04-21 17:45 /backup/test/part-m-00000

3.创建新的表结构

hbase(main):032:0> create 'emp', 'cf1', 'cf2'
0 row(s) in 1.0590 seconds

4.将备份导入到新表

# hbase org.apache.hadoop.hbase.mapreduce.Import emp hdfs://sht-sgmhadoopnn-01:9011/backup/test

或采用以下写法

# hbase org.apache.hadoop.hbase.mapreduce.Import emp /backup/test

输出log

[root@sht-sgmhadoopdn-02 exp]# hbase org.apache.hadoop.hbase.mapreduce.Import emp hdfs://sht-sgmhadoopnn-01:9011/backup/test

二.复制

1. 新建表结构

hbase(main):035:0> create 'emp1', 'cf1', 'cf2'
0 row(s) in 1.0610 seconds

2. 将老表数据复制到新表

# hbase org.apache.hadoop.hbase.mapreduce.CopyTable --new.name=emp1 test

输出log
