    Hi Anonymous, I'm using vscode + spark(docker) to run the code. I found the problem, it was my firewall blocking, so here is the code to read a file outside a Microsoft service:

     

    from pyspark.sql import SparkSession
    
    spark = (SparkSession.builder.config("spark.jars.packages", "org.apache.hadoop:hadoop-azure:3.3.1")
             .appName("Fabric").getOrCreate())
    
    spark.conf.set("fs.azure.account.auth.type", "OAuth")
    spark.conf.set("fs.azure.account.oauth.provider.type", "org.apache.hadoop.fs.azurebfs.oauth2.ClientCredsTokenProvider")
    spark.conf.set("fs.azure.account.oauth2.client.id", service_principal_id)
    spark.conf.set("fs.azure.account.oauth2.client.secret", service_principal_password)
    spark.conf.set("fs.azure.account.oauth2.client.endpoint", f"https://login.microsoftonline.com/{tenant_id}/oauth2/token")
    spark.conf.set("spark.sql.execution.arrow.pyspark.enabled", "true")
    spark.conf.set("spark.sql.files.ignoreCorruptFiles", "true")
    
    table_name = ''
    
    df = spark.read.format("parquet").load(f"abfss://{workspace_name}@onelake.dfs.fabric.microsoft.com/{lakehouse_name}.Lakehouse/Tables/{table_name}/*.parquet")
    
    df.show()
