Hive JDBC连接设置或与MySQL的映射 [英] Hive JDBC connection setting or mapping with MySQL

问题描述

我不熟悉大数据；从技术上讲，我是Java开发人员，因此决定学习大数据概念.我只能够安装Hadoop和Hive，现在我想将Java程序连接到Hive.我已经将MySQL配置为后端数据库.

I am new to big data; technically I am a Java developer and decided to learn big data concepts. I am just able to install Hadoop and Hive, and now I want to connect my Java program to Hive. I have configured MySQL as a back-end db.

尝试使用Google，并找到了一些Java程序示例，他们在其中使用了类似URL jdbc:hive2://172.16.149.158:10000/default,"",""的内容.

Tried to Google it and found a few Java program sample where they are using something like this URL jdbc:hive2://172.16.149.158:10000/default,"","".

我的问题是我没有在hive-sites.xml中进行任何此类设置.我应该在哪里进行这些设置，或者如果不是在哪里可以找到我应该使用的设置?

My question is I didn't made any setting like this in hive-sites.xml. Where should I made these setting or if not than where to find out which setting I should use?

推荐答案

端口10000是HiveServer2的默认端口，它使客户端能够对Hive执行查询.

Port 10000 is the default port for HiveServer2, which enables clients to execute queries against Hive.

通过属性hive.server2.thrift.port

<property>
  <name>hive.server2.thrift.port</name>
  <value>10000</value>
</property>

此外，URL中的default是默认的Hive数据库.

Also, the default in the URL is the default Hive database.
