Hive - mysql ssl warning

gitava commented 4 years ago

whenever to run hive commands, the following annoying inof showed up...

Sun Jun 28 11:05:09 UTC 2020 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.

二、解决方法根据告警提示有两种解决方法：

1.设置useSSL=false 这里有个坑就是hive的配置文件是.XML格式，而在xml文件中&amp；才表示&，所以正确的做法是在Hive的配置文件中，如hive-site.xml进行如下设置

  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true&amp;useSSL=false</value>
    <description>JDBC connect string for a JDBC metastore</description>
  </property>

2.设置useSSL = true并为服务器证书验证提供信任库。

server version

  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://192.168.33.102:3306/hive?createDatabaseIfNotExist=true&amp;useSSL=false</value>
    <description>
      JDBC connect string for a JDBC metastore.
      To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.
      For example, jdbc:postgresql://myhost/db?ssl=true for postgres database.
    </description>
  </property>
