開發準備：

　　jdk1.8.45

　　hbase-1.2.2（windows下和linux個留一份）

　　hadoop-2.7.2（linux一份）

　　Linux系統（centos或其它）

　　Hadoop安裝環境

　　HBase安裝環境

?

具體操作步驟如下：

1.?Eclipse中新建Maven項目， type為maven-archetype-quickstart，工程名為MyHBase

2.?將hadoop集群和hbase集群的配置文件放到如下路徑:

/src/main/resources/hadoop /src/main/resources/hbase ? 3. 將配置路徑加入到classpath中： ? ? 　　

4.?最終的目錄結構

?

5. 編輯hbase-site.xml文件內容為：

　　

6. 將Linux下部署的HBase集群下的lib目錄拷貝到Windows下，并在eclipse中將lib（里面的hadoop庫可能與安裝的hadoop版本不一致，后續可以考慮版本統一）下的所有庫添加到工程：

7. 新建類HBaseTest ，內容如下：

8. 如果報錯查看日志，修改C:\Windows\System32\drivers\etc\HOSTS:

　　112.120.41.159 hadoop

9.?右鍵-->Run as -->java application.
