应用sqoop将MySQL数据库中的数据导入Hbase

转自：http://www.bwxxkj.com/a/jishuzhongxin/xingyeyingyong/2012/0327/88943.html

前提：安装好 sqoop、hbase。

教材气的人，他们彼此建树友情，是很是轻易的；要他破损已有的友情，倒是一件难事。正如黄金的器皿一样，是不轻易破裂的；假如破损了，要修补它，使它恢答复复兴状，倒是最轻易的事。下载jbdc驱动：mysql-connector-java-5.1.10.jar

将?mysql-connector-java-5.1.10.jar?复制到 /usr/lib/sqoop/lib/ 下

MySQL导入HBase号令：
sqoop import --connect jdbc:mysql://10.10.97.116:3306/rsearch --table researchers --hbase-table A --column-family person --hbase-row-key id --hbase-create-table --username ""root"" -P

申明：
--connect jdbc:mysql://10.10.97.116:3306/rsearch 默示长途或者本地 Mysql 办事的URI，3306是Mysql默认监听端口，rsearch是数据库，若是其他数据库，如Oracle，只需批改URI即可。
--table researchers ?默示导出rsearch数据库的researchers表。
--hbase-table A ?默示在HBase中建树表A。
--column-family person 默示在表A中建树列族person。
--hbase-row-key id ?默示表A的row-key是researchers表的id字段。
--hbase-create-table 默示在HBase中建树表。
--username ""root"" 默示应用用户root连接Mysql。

重视：

HBase的所有节点必须可以或许接见MySQL数据库，不然会呈现如下错误：
java.sql.SQLException: null， ?message server: "Host ""10.10.104.3"" is not allowed to connect to this MySQL server"

?

1. 在MySQL数据库办事器节点上履行以下号令容许长途机械应用响应用户接见本地数据库办事器：??
2. [root＠gc01vm6?htdocs]?＃?/opt/lampp/bin/mysql??
3. ??
4. mysql>?use?mysql;??
5. Database?changed??
6. mysql>?GRANT?ALL?PRIVILEGES?ON?rsearch.*?TO?""root""＠""10.10.104.3""?IDENTIFIED?BY?""""?WITH?GRANT?OPTION;???
7. mysql>?GRANT?ALL?PRIVILEGES?ON?rsearch.*?TO?""root""＠""10.10.104.5""?IDENTIFIED?BY?""""?WITH?GRANT?OPTION;???
8. mysql>?GRANT?ALL?PRIVILEGES?ON?rsearch.*?TO?""root""＠""10.10.104.2""?IDENTIFIED?BY?""""?WITH?GRANT?OPTION;???

在MySQL数据库办事器节点上履行以下号令容许长途机械应用响应用户接见本地数据库办事器： [root＠gc01vm6 htdocs] ＃ /opt/lampp/bin/mysql mysql> use mysql; Database changed mysql> GRANT ALL PRIVILEGES ON rsearch.* TO ""root""＠""10.10.104.3"" IDENTIFIED BY """" WITH GRANT OPTION; mysql> GRANT ALL PRIVILEGES ON rsearch.* TO ""root""＠""10.10.104.5"" IDENTIFIED BY """" WITH GRANT OPTION; mysql> GRANT ALL PRIVILEGES ON rsearch.* TO ""root""＠""10.10.104.2"" IDENTIFIED BY """" WITH GRANT OPTION;
这里10.10.104.2，10.10.104.3，10.10.104.5 是HBase节点。
