Hello anonymous user,

Thanks for the question and using MS Q&A platform.

From the error message it clearly says that - "com.microsoft.spark.notebook.msutils.InvalidCredentialsException: Please provide at least one of LinkedService name, accountKey or sasToken for authorization"

Currently these are the three authentication types are supported when trigger mount operation, via LinkeService, via accountKey and via sastoken.

Method1: Using Linked Service

mssparkutils.fs.mount(  
    "abfss://<FILESYSTEMNAME>@<STORAGENAME>.dfs.core.windows.net/", #ADLS GEN 2 PATH  
    "</MOUNTNAME>", #Mount Point Name  
    { "linkedService" : "<REPLACE LINKED SERVICE NAME>"}  
)  

Method2: Using SAS Token

mssparkutils.fs.mount(  
    "abfss://<FILESYSTEMNAME>@<STORAGENAME>.dfs.core.windows.net/", #ADLS GEN 2 PATH  
    "</MOUNTNAME>", #Mount Point Name  
    { "sasToken" : "<REPLACE SAS TOKEN KEY>"}  
)  

Method3: Using Account Key

mssparkutils.fs.mount(  
    "abfss://<FILESYSTEMNAME>@<STORAGENAME>.dfs.core.windows.net/", #ADLS GEN 2 PATH  
    "</MOUNTNAME>", #Mount Point Name  
    { "accountKey" : "<REPLACE AACOUNT KEY>"}  
)  

Hope this will help. Please let us know if any further queries.
