SQOOP——MySQL 和 HDFS 的桥梁
将数据从 <em>mysql</em> import 到 HDFS 中我们要使用 <em>mysql</em> 的话,意味着要对其进行连接,自然使用 JDBC(Java Data Base Connectivity)。在之前配置 hive 的 <em>mysql</em> 时,我们已将 <em>mysql</em>-connector-java-5.1.10.jar 拷贝到 hive/lib 目录下,[root@hadoop0 ~]# cp $HIVE_HOME/lib
使用Sqoop将MySQL与HDFS数据导入导出
一、拷贝<em>mysql</em>数据表到<em>hdfs</em>上 1.确保<em>mysql</em>可以远程连接, 防火墙等已关闭或开端口, hadoop已启动, <em>hdfs</em>可访问(没有处于安全模式,如果处于点击这里) 2.确保<em>hdfs</em>上不存在目标文件夹, <em>sqoop</em>会自动生成文件夹, 若已存在则<em>报错</em>,要么加上--delete-target-dir 3.命令如下, 参数自行修改, <em>mysql</em>所在IP为192.168.203.7, 用户名密码...
