任何人都可以建议我们如何放弃桌子？

Answer 1

基本上，您需要更新您创建的HDFS路径的元数据。

从Hive Metastore计算机运行此程序。

例如：

/ usr / hdp / current / hive / bin / metatool -updateLocation hdfs：// nameserviceID / external hdfs：//namenode.fqdn：8020 / external

验证，运行：

/ usr / hdp / version-number / hive / bin / metatool -listFSRoot

确保列出了新路径。

这里还有其他一些解决方案： java.lang.IllegalArgumentException: Wrong FS: , expected: hdfs://localhost:9000

尝试删除数据库时出错
