Error: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000: java.net.ConnectException: 拒絕連接 (Connection refused) (state=08S01,code=0)

一：啟動hiveserver2服務

 

 

二：啟動beeline

 

 

三：連接hiveserver2（下面的1000000端口號適當改小寫因為其超出最大端口號的范圍建議改為10000）

 

 

 

 

如果啟動不成功實現我們先檢查以下兩個文件配置是否正確

1）hadoop文件夾下面的core-site.xml中的內容

<property>
        <name>hadoop.proxyuser.zhang.hosts</name>
        <value>*</value>
    </property>
    <property>   
        <name>hadoop.proxyuser.zhang.groups</name>
            <value>*</value>
    </property>

 

 

2）hive文件夾下hive-site.xml中的內容

 

<property>
		<name>hive.server2.thrift.port</name>
		<value>1000000</value>
	</property>
	<property>
	 	<name>hive.server2.thrift.bind.host</name>
	    	<value>localhost</value>
	</property>

 

　　

 

 

可能出現的錯誤：

 

Error: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000: java.net.ConnectException: 拒絕連接 (Connection refused) (state=08S01,code=0)

 

 

解決方案1：殺死占用端口進程（https://blog.csdn.net/xiaoqiu_cr/article/details/81634434）

解決方案2：直接修改配置文件的端口號（我是采用的此種解決方法）
