Hadoop Fiware Cosmos配置单元授权问题

我正在使用的共享实例（意味着我没有根权限）。到今天为止，我已经成功地使用jdbc和hive CLI远程访问和管理了hive中的表。 但现在我在启动Hive CLI时遇到以下错误：

log4j:ERROR Could not instantiate appender named "EventCounter".

Logging initialized using configuration in jar:file:/usr/local/apache-hive-0.13.0-bin/lib/hive-common-0.13.0.jar!/hive-log4j.properties

在错误出现之前，我没有对代码或命令做任何更改，在谷歌搜索之后，我也没有找到任何有效的解决方案

如果有人能告诉我问题在哪里，或者如何找到它，或者更好地解决它，我将不胜感激

提前谢谢

HiveServer2（HiveJDBC服务）是一种非常不稳定的软硬件。在我们的Prod集群中，我们每天都有一个CRON任务来重新启动每个实例，即使如此，有时它也会爆发内存错误，然后挂起，说

连接被拒绝

，就像您所展示的那样。打开一张Hadoop管理员的票证，让他/她重新启动该死的服务

另一方面，

org.apache.hadoop.log.metrics.EventCounter

消息闻起来像是有人试图在某处更改共享配置（或试图升级一些JAR），现在Hive认为它运行在非常非常旧的hadoop版本上

中的评论这些问题的原因是Cosmos中的蜂窝升级。以下是更全面的解释和解决方案：

谢谢你的帮助！我已经让管理员调查过了。关于共享配置，我可以检查，甚至修复吗？我该往哪里看？看来你不是唯一一个受苦的人：stackoverflow.com/questions/321341/my-hive-client-stopped-working-with-cosmos-instance/32134464
