最近因為生產環境hbase中某張表的數據要導出到測試環境（數據不多，大概200W條左右），如果用程序掉接口導入的話太慢，所以考慮直接用 hbase的功能來導入導出。因為此次是實驗，所以我在正式環境建了一張小表，只有兩條數據，目的是將它導入到一張新表中（空表，但是表結構一樣）

上述紅色字體輸出已提示導出了兩條數據了，因為我有3個datanode，加上數據比較少，所以肯定只會在一台datanode上有導出文件。 如果數據很多，可能每個datanode節點都會有導出文件，至於在哪台datanode上你就需要找一下/home/hadoop目錄下有沒有xyz目 錄了。
我這找到后文件如下：
[hadoop@slave2 ~]$ cd xyz/
[hadoop@slave2 xyz]$ ls
part-m-00000 _SUCCESS
[hadoop@slave2 xyz]$ ls
part-m-00000 _SUCCESS
開始新建一張新表，表結構和xyz表一樣
hbase(main):001:0> create 'zzz','cf1'
0 row(s) in 2.0490 seconds
0 row(s) in 2.0490 seconds
然后開始導入，這里我就利用導出文件在哪我就在哪導入了。當然你也可以拿這個part-m-00000文件到其余的datanode上導入，
順便友情提醒一下，如果導出的數據很多，你導入的時候千萬別把所有的part-m-0000*文件都放到一個目錄下開始導入，肯定會失敗的！你只能把part-m-0000*文件一個個開始導入。

查看zzz表中的數據
hbase(main):003:0> scan 'zzz'
ROW
COLUMN+CELL
10000 column=cf1:val, timestamp=1345598242644, value=china
20000 column=cf1:val, timestamp=1345598283332, value=zengzhunzhu
n
2 row(s) in 0.0410 seconds
這樣基本就完成了hbase表中的數據我們可以轉化為mapreduce任務進程開始導出導入。當然也可以這么備份的。
