Python 使用Databricks在Apache Spark中装载Azure Data Lake时出错

我正在尝试用ApacheSpark中的以下Python代码装载Azure数据湖

def check(mntPoint):
  a= []
  for test in dbutils.fs.mounts():
    a.append(test.mountPoint)
  result = a.count(mntPoint)
  return result

mount = "/mnt/lake"

if check(mount)==1:
  resultMsg = "<div>%s is already mounted. </div>" % mount
else:
  dbutils.fs.mount(
  source = "wasbs://root@adlsprexxxxxdlsdev.blob.core.windows.net",
  mount_point = mount,
  extra_configs = {"fs.azure.account.key.adlspretxxxxdlsdev.blob.core.windows.net":""})
  resultMsg = "<div>%s was mounted. </div>" % mount

displayHTML(resultMsg)

完全错误如下所示：

ExecutionError                            Traceback (most recent call last)
<command-3313750897057283> in <module>
      4   resultMsg = "<div>%s is already mounted. </div>" % mount
      5 else:
----> 6   dbutils.fs.mount(
      7   source = "wasbs://root@adlsprexxxxxxxkadlsdev.blob.core.windows.net",
      8   mount_point = mount,

/local_disk0/tmp/1619799109257-0/dbutils.py in f_with_exception_handling(*args, **kwargs)
    322                     exc.__context__ = None
    323                     exc.__cause__ = None
--> 324                     raise exc
    325             return f_with_exception_handling
    326 

ExecutionError回溯（最近一次调用）
在里面
4 resultsg=“%s已装入。”%mount
5其他：
---->6 dbutils.fs.mount(
7来源=”wasbs://root@adlsprexxxxxxkadlsdev.blob.core.windows.net“，
8安装点=安装，
/本地磁盘0/tmp/1619799109257-0/dbutils.py在f_中，带有异常处理（*args，**kwargs）
322 exc.\uuuuu上下文\uuuuuu=无
323 exc.\原因\无
-->324升exc
325带异常处理的返回f_
326

有人能告诉我如何解决这个问题吗？

你需要提供存储密钥，而现在你有空字符串。通常人们将存储密钥放入Azure KeyVault（并将其装载为secret scope）或使用Databricks烘焙的secret scope，然后通过

dbutils.secrets.get

（如图所示）：

dbutils.fs.mount(
来源=”wasbs://root@adlsprexxxxxdlsdev.blob.core.windows.net“，
安装点=安装，
extra_configs={“fs.azure.account.key.adlspretxxxxdlsdev.blob.core.windows.net”：
dbuitils.secrets.get（作用域名称，秘密名称）}）
