篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了sqoop把hive表数据导入到mysql中相关的知识，希望对你有一定的参考价值。
应用：
SQOOP是用于对数据进行导入导出的。
(1)把mysql、Oracle等数据库中的数据导入到HDFS、Hive、HBase中
(2)把HDFS、Hive、HBase中的数据导出到MySQL、Oracle等数据库中
1.把数据从mysql导入到hdfs(默认是/user/<username>)中
sqoop import --connect jdbc:mysql://hadoop0:3306/hive --username root --password admin --table TBLS --fields-terminated-by '\\t' --null-string '**' -m 1 --append --hive-import
sqoop import --connect jdbc:mysql://hadoop0:3306/hive --username root --password admin --table TBLS --fields-terminated-by '\\t' --null-string '**' -m 1 --append --hive-import --check-column 'TBL_ID' --incremental append --last-value 6
2.把数据从hdfs导出到mysql中
sqoop export --connect jdbc:mysql://hadoop0:3306/hive --username root --password admin --table ids --fields-terminated-by '\\t' --export-dir '/ids'
3.设置为作业，运行作业
sqoop job --create myjob -- import --connect jdbc:mysql://hadoop0:3306/hive --username root --password admin --table TBLS --fields-terminated-by '\\t' --null-string '**' -m 1 --append --hive-import
4. 导入导出的事务是以Mapper任务为单位。例子：
1、解压sqoop：
[root@i-love-you local]# tar -zxvf sqoop-1.4.4.bin__hadoop-2.0.4-alpha.tar.gz2、把 mysql-connector-java-5.1.33-bin.jar 拷贝到 sqoop 的lib 目录里
3、把hive表里数据导入到mysql里面去：
[root@i-love-you sqoop]# bin/sqoop export --connect jdbc:mysql://192.168.1.1:3306/bbs --username root --password mysqladmin --table bbs_info --fields-terminated-by '\\001' --export-dir '/hive/bs_info';
