在Ubuntu中执行hive cli时,出现以下错误消息:

hadoopgudi@hadoopgudi-VirtualBox:~$ hive
SLF4J: Class path contains multiple SLF4J bindings.

Hive-on-MR is deprecated in Hive 2 and may not be available in the future

using Hive 1.X releases.

**FAILED: HiveException java.lang.RuntimeException: Unable to instantiate

因此,我已经尝试了有关此错误的所有社区论坛。在所有提到的地方,您都必须删除在cli上运行hive命令时创建的metastore_db文件。然后尝试以下命令:

schematool -dbType mysql -initSchema

但是,我没有找到metastore_db文件或任何这种格式的文件。 因此,我想再次运行schematool命令来检查它是否可以重新启动mysql数据库中的metastore模式。但是,再次遇到流程失败,如下所示:

hadoopgudi@hadoopgudi-VirtualBox:/$ schematool -dbType mysql -initSchema

你们能帮我解决这个问题吗? 我想尝试重新发送元存储过程,但未成功,因为我无法定位并命令实现相同的目标?
