Question

当我尝试连接Hive Mysql metastore时，由于连接被拒绝而引发错误。下面给出了pom.xml，hive-site.xml和代码中的详细信息

    SELECT DISTINCT 
    `media`.`id`,`media`.`description`, 
    `keywords`.`id` AS `keywords.id`, 
    `keywords->media_keywords`.`id` AS `keywords.media_keywords.id`, 
    `keywords->media_keywords`.`media_id` AS `keywords.media_keywords.media_id`, 
    `keywords->media_keywords`.`keyword_id` AS `keywords.media_keywords.keyword_id` 

    FROM database.media 

    LEFT OUTER JOIN 
    ( 
        `media_keywords` AS `keywords->media_keywords` 

        INNER JOIN `keywords` AS `keywords` 
        ON `keywords`.`id` = `keywords->media_keywords`.`keyword_id`
    ) 

    ON `media`.`id` = `keywords->media_keywords`.`media_id` 

    WHERE 
    ( 
            (`media`.`description` LIKE '%dog%' ) 

            OR `keywords`.`id` IN (100) 
    )

    AND NOT 
    ( 
            (`media`.`description` LIKE '%cat%' ) 

            OR `keywords`.`id` IN (400,500)
    )

    GROUP BY `media`.`id` ;

可能有两个原因：

您的配置单元metastore似乎已被锁定，spark无法访问。您需要从元存储中删除锁定文件。
```
rm metastore_db/*.lck
```
此外，您还需要检查Metastore服务器是否已启动并正在运行。尝试以下代码：
```
ps -ef | grep metastore
```

如果没有，您可以尝试查看日志：/var/log/hive/hivemetastore.log

希望这会有所帮助：）
