Sqoop_ 从 hive 导到mysql常遇九问题总结(转)
以前以为版本不同，遇到的问题就不同，后来发现，无论是新版本，还是老版本，遇到的问题大部分都是相同的。下面解决问题的方法仅供借鉴
1.拒绝连接的错误表现是什么？
2.表不存在该如何解决？
3.null字段填充符该如何指定？
环境
hive 版本hive-0.11.0
sqoop 版本 sqoop-1.4.4.bin__hadoop-1.0.0
从hive导到mysql
mysql 表 mysql> desc cps_activation;
+————+————-+——+—–+———+—————-+
| Field | Type | Null | Key | Default | Extra |
+————+————-+——+—–+———+—————-+
| id | int(11) | NO | PRI | NULL | auto_increment |
| day | date | NO | MUL | NULL | |
| pkgname | varchar(50) | YES | | NULL | |
| cid | varchar(50) | YES | | NULL | |
| pid | varchar(50) | YES | | NULL | |
| activation | int(11) | YES | | NULL | |
+————+————-+——+—–+———+—————-+
6 rows in set (0.01 sec) hive表 hive> desc active;
OK
id int None
day string None
pkgname string None
cid string None
pid string None
activation int None

导出数据到MySQL，当然数据库表要先存在，否则会报错
此错误的原因为sqoop解析文件的字段与MySql数据库的表的字段对应不上造成的。因此需要在执行的时候给sqoop增加参数，告诉sqoop文件的分隔符，使它能够正确的解析文件字段。hive默认的字段分隔符为’\001′
3. null字段填充符需指定(没有指定null字段分隔符，导致错位)
[hadoop@hs11 ~]$ sqoop export –connect jdbc:mysql://10.10.20.11/test –username root –password admin –table test –export-dir /user/hive/warehouse/actmp –input-fields-tminated-by ‘\001′
