我在单节点 centos7 上安装了 Hadoop 3.2.1 和 hadoop 顶部安装了 hive 3.1.2,并希望与 Presto 搜索引擎集成,这样我就可以看到 hive 的数据库到 presto-server-0.229.Hive 运行良好并且能够创建表,我已经在官方文档的帮助下完成了 presto-server-0.229 的安装和配置。但我无法从 presto 访问数据库。
Here are my all configuration details:
Hive-site.xml:
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://10.0.0.96/metastore_db?createDatabaseIfNotExist=true</value>
