问题摘要 试图将一个工作中的hive安装连接到一个正常运行的mysql数据库来创建hcatalog (也就是metastore)，已经按照规定配置了hive-site.xml--并且正在使用java 8来解决各种线程。
确认了hive交互的bash cli。

user@node:hive
Hive Session ID = 66da2903-6e11-43e6-95de-84bf41b1b977
Logging initialized using configuration in jar:file:/home/hadoop/apache-hive-3.1.2-bin/lib/hive-common-3.1.2.jar!/hive-log4j2.properties Async: true
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.

mysql从计划中的用户成功连接。

mysql -s -h 192.168.2.40 -u hiveuser -pNEVERYOUMIND
mysql: [Warning] Using a password on the command line interface can be insecure.

努力调试自己--搜索jdbcuriparseexception。
在google上查遍了所有的地方，以确定在hive的代码中出现了这种情况--只有这个模块与之接近--https://github.com/apache/hive/blob/master/beeline/src/java/org/apache/hive/beeline/beeline.java commit 91ab242 ，第1190行，但由于在我的输出中没有beeline调用（也许是在...11更多的？

try {
            jdbcConnectionParams = Utils.extractURLComponents(jdbcURL, new Properties());
          } catch (JdbcUriParseException e) {

这里是hive-site.xml。

当使用mysql cli和workbench时，数据库用户hiveuser连接并存在--并且它可以创建表。
java和mysql连接器已经尝试了各种包括java 11和java 8 - mysql版本5连接器和8连接器 - 所有呈现相同的结果 - 所以我不确定这是jdbc相关的 - - 另一种观点将是感激地收到。
