mssparkutils.fs.mv is giving : java.io.IOException: when trying to move files

[rautd]

Hi All,

I am trying to move files from one a workspace in one subscription to another workspace in another subscription using mssparkutils.fs.mv. mssparkutils.fs.cp is working file. I am able to copy files but move is giving error.

We have created trusted workspace between the subscription. Also created shortcut for second workspace. Below is the code that I am using - 

import os

for file in mssparkutils.fs.ls(scripdeltapath):  

    updated_path = os.path.join(stagingdeltapath, file.name) 

    print(f"Moving from {file.path} -> {updated_path}")

    try:

        mssparkutils.fs.cp(file.path,updated_path)

    except Exception as e:

           print(str(e))

        mssparkutils.notebook.exit("Error: Something went wrong!", status="error")

Let me know if you need more infromation.

Thanks,

Deepmala

Hi @rautd 

I used your code to move files from one workspace to another workspace without experiencing any error. I tried mssparkutils.fs.mv and mssparkutils.fs.cp, both worked. What error did you get when moving files? Is there any error message?

In addition, if you move files to a workspace which locates in the same Fabric Capacity as the source Workspace does, will it succeed?

More information: in my testing, I was using ABFS paths and moving files across workspaces within the same Fabric Trial Capacity. 

Best Regards,
Jing

Hi,

For me as well, cp worked but mv was giving IOException error as mentioned in my post. Also I have created shortcuts and by using that shortcuts I was trying to move files from workspace to another in two different subcriptions.

Hi @rautd have you tried adding the parameters that create the destinations directory?

mssparkutils.fs.mv(file.path,updated_path,True,True)

From MS docs: Microsoft Spark Utilities (MSSparkUtils) for Fabric - Microsoft Fabric | Microsoft Learn

mssparkutils.fs.mv('source file or directory', 'destination directory', True) # Set the last parameter as True to firstly create the parent directory if it does not exist

mssparkutils.fs.mv('source file or directory', 'destination directory', True, True) # Set the third parameter to True to firstly create the parent directory if it does not exist. Set the last parameter to True to overwrite the updates.
