hive连接mysql出现 useSSL=false, or set useSSL=true

关于hive连接mysql出现 WARN Establishing SSL connection without server’s identity verification is not recommended.······· useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

修改hive的配置文件 （第10行） ：

[root@hadoop102 conf]# pwd
/opt/module/hive/conf
[root@hadoop102 conf]# vim hive-site.xml 

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

将第10行改为：

jdbc:mysql://hadoop102:3306/metastore?createDatabaseIfNotExist=true&useSSL=false

修改后如下:

[root@hadoop102 conf]# pwd
/opt/module/hive/conf
[root@hadoop102 conf]# vim hive-site.xml 

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

之前的：
Mon Nov 23 22:01:11 CST 2099 WARN: 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.
