如何在databricks文件系统中移动具有相同扩展名的文件? [英] How to move files of same extension in databricks files system?

问题描述

当我尝试在DBFS中使用*移动文件时，遇到文件未找到异常.这里，源目录和目标目录都在DBFS中.我在dbfs目录中有一个名为"test_sample.csv"的源文件，并且我正在笔记本单元中使用以下命令，

I am facing file not found exception when i am trying to move the file with * in DBFS. Here both source and destination directories are in DBFS. I have the source file named "test_sample.csv" available in dbfs directory and i am using the command like below from notebook cell,

dbutils.fs.mv("dbfs:/usr/krishna/sample/test*.csv", "dbfs:/user/abc/Test/Test.csv")

错误:

java.io.FileNotFoundException: dbfs:/usr/krishna/sample/test*.csv

感谢您的帮助.谢谢.

推荐答案

dbutils当前不支持通配符.您可以移动整个目录:

Wildcards are currently not supported with dbutils. You can move the whole directory:

dbutils.fs.mv("dbfs:/tmp/test", "dbfs:/tmp/test2", recurse=True)

或仅一个文件:

dbutils.fs.mv("dbfs:/tmp/test/test.csv", "dbfs:/tmp/test2/test2.csv")

如下面的注释中所述，您可以使用python来实现此通配符逻辑.另请参见以下 answer 中的一些代码示例.

As mentioned in the comments below, you can use python to implement this wildcard-logic. See also some code examples in my following answer.
