【解决方案1】：

本质上，您需要更新您创建的 HDFS 路径的元数据。

从 Hive Metastore 机器上运行它。

例如：

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

要验证，请运行：

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

确保列出您的新路径。

这里还有一些其他的解决方案： java.lang.IllegalArgumentException: Wrong FS: , expected: hdfs://localhost:9000
