1、準備工作：

1.1 HBase已經建立並且正常

1.2 檢查hbase狀態

[root@namenode ~]# hbase shell

15/07/13 10:42:47 INFO Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available

HBase Shell; enter 'help<RETURN>' for list of supported commands.

Type "exit<RETURN>" to leave the HBase Shell

Version 1.0.0-cdh5.4.3, rUnknown, Wed Jun 24 19:34:50 PDT 2015

hbase(main):001:0> status

3 servers, 0 dead, 1.0000 average load

hbase(main):002:0>

出現以上情況為hbase可用。

1.3 嘗試建立資料表

hbase(main):069:0> create 'member','member_id','address','info'

0 row(s) in 1.3860 seconds

1.4 插入模擬資料

hbase(main):032:0> put'member','scutshuxue','info:age','24'

'

put'member','xiaofeng','address:province','guangdong'

put'member','xiaofeng','address:city','jieyang'

put'member','xiaofeng','address:town','xianqiao'

0 row(s) in 0.0790 seconds

hbase(main):033:0>

hbase(main):034:0* put'member','scutshuxue','info:birthday','1987-06-17'

0 row(s) in 0.0060 seconds

hbase(main):035:0>

hbase(main):036:0* put'member','scutshuxue','info:company','alibaba'

hbase(main):060:0* put'member','xiaofeng','address:town','xianqiao'

0 row(s) in 0.0060 seconds

1.5 檢索資料

hbase(main):061:0> scan 'member'

ROW COLUMN+CELL

scutshuxue column=address:city, timestamp=1436753702560, value=hangzhou

scutshuxue column=address:contry, timestamp=1436753702509, value=china

scutshuxue column=address:province, timestamp=1436753702534, value=zhejiang

scutshuxue column=info:age, timestamp=1436753702377, value=24

scutshuxue column=info:birthday, timestamp=1436753702430, value=1987-06-17

scutshuxue column=info:company, timestamp=1436753702472, value=alibaba

xiaofeng column=address:city, timestamp=1436753702760, value=jieyang

xiaofeng column=address:contry, timestamp=1436753702703, value=china

xiaofeng column=address:province, timestamp=1436753702729, value=guangdong

xiaofeng column=address:town, timestamp=1436753702786, value=xianqiao

xiaofeng column=info:birthday, timestamp=1436753702612, value=1987-4-17

xiaofeng column=info:company, timestamp=1436753702678, value=alibaba

xiaofeng column=info:favorite, timestamp=1436753702644, value=movie

2 row(s) in 0.0870 seconds

1.6 資料遷移環境檢查

登陸hbase所在的伺服器，通常來說是namenode那臺伺服器。檢查一下已存在的目錄

[root@namenode ~]# hadoop fs -ls /

Found 3 items

drwxr-xr-x - hbase hbase 0 2015-07-13 10:02 /hbase

drwxrwxrwt - hdfs supergroup 0 2015-07-13 10:12 /tmp

drwxr-xr-x - hdfs supergroup 0 2015-07-13 10:12 /user

1.7開始匯出HBase的表

hbase org.apache.hadoop.hbase.mapreduce.Export member /tmp/member

member是表名 後面的是hdfs檔案系統的目錄

2. 資料恢復

2.1將原資料表清空

hbase(main):063:0> disable 'member'

0 row(s) in 1.3760 seconds

hbase(main):065:0> drop 'member'

0 row(s) in 0.8590 seconds

hbase(main):066:0> list

TABLE

0 row(s) in 0.0100 seconds

可以看出，member表已經不存在了。

2.2建立表結構

用export匯出的需要用import匯入。但是匯入之前表結構應該先建立。

hbase(main):069:0> create 'member','member_id','address','info'

0 row(s) in 1.3860 seconds

[root@namenode ~]# hbase org.apache.hadoop.hbase.mapreduce.Import member /tmp/member

hbase(main):071:0> scan 'member'

ROW COLUMN+CELL

0 row(s) in 0.0220 seconds

恢復之前

hbase(main):072:0> scan 'member'
