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>
          <description>metadata is stored in a MySQL server</description>
          </property>

          <property>
          <name>javax.jdo.option.ConnectionDriverName</name>
          <value>com.mysql.jdbc.Driver</value>
          <description>MySQL JDBC driver class</description>
          </property>

          <property>
          <name>javax.jdo.option.ConnectionUserName</name>
          <value>hiveuser</value>
          <description>user name for connecting to mysql server </description>
          </property>

          <property>
          <name>javax.jdo.option.ConnectionPassword</name>
          <value>hivepassword</value>
          <description>password for connecting to mysql server </description>
          </property>

          <property>
          <name>hive.metastore.uris</name>
          <value>thrift://10.0.0.96:9083</value>
          <description>Hive metastore Thrift server</description>
          </property>

Presto .229 不支持 Hive 3。

当前支持 Hive 3:

  • Starburst Presto 323-econnector.name尽管如此hive-hadoop2
  • 通过 Qubole 平台上的 Presto(我不知道配置细节)。

Presto 在 Hive 3 支持方面的工作正在进行中,您可以在此处跟踪它:https ://github.com/prestosql/presto/issues/1218 。

由于您可能会遇到不适合 SO 的后续故障排除问题,因此我建议您加入#troubleshootingPresto Community Slack上。如果您使用Starburst Presto选项,则#starburst该松弛处也有通道。
