sqoop 连接 mysql 小bug

 Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"SQOOP"' at line 1

 

解决方法：

mysql> drop database if exists sqoop;
 
mysql> create database sqoop;
 
mysql> SET GLOBAL sql_mode = ANSI_QUOTES; 
解释：

sql_mode: 定义了MySQL支持的sql语法，对数据的校验等等

select @@sql_mode；查看我们当前数据库的sql_mode；
