Using dbutils.fs.ls gives overlap error.

I created a schema with that route as a managed location.

(abfss://~~@~~.dfs.core.windows.net/dejeong)

And an external table named 'first_table' was created in the corresponding path.

(abfss://~~@~~.dfs.core.windows.net/dejeong/first_table)

The results of the dbutils.fs.ls and sql list clauses are different for the three paths.

%python

dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong") --> managed location overlaps error

dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong/__unitystorage") --> managed location overlaps error

dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong/first_table") --> out[3]

%sql

list"abfss://~~@~~.dfs.core.windows.net/dejeong" --> out[2]

list "abfss://~~@~~.dfs.core.windows.net/dejeong/__unitystorage" --> managed location overlaps error

list "abfss://~~@~~.dfs.core.windows.net/dejeong/first_table" -->out[2]

Is this a bug in dbutils.fs.ls?

Or did I do something wrong?

I want to navigate parent path with dbutils.fs.ls syntax.

@jin park :

It seems like there is an overlap in the path when you use dbutils.fs.ls() to list the contents of

abfss://~~@~~.dfs.core.windows.net/dejeong, which is the managed location. This may be due to the fact that the managed location is also a path, and this is causing a conflict. To navigate to the parent path, you can use dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong/"), with a trailing slash at the end of the path. This should list the contents of the parent directory without causing any conflicts.

Alternatively, you can try using dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong/__internal")

, which is the internal directory where managed tables are stored, instead of __unitystorage.

It's also worth noting that the behavior of dbutils.fs.ls() and list in SQL may differ, as they are different methods and may handle paths differently.

dbutils.fs.ls("abfss://~~@~~.dfs.core.windows.net/dejeong/ ")

This route still gives me an error
